Data are mediated through this human instrument, rather than through inventories, questionnaires, or machines. Qualitative and quantitative data generation techniques can be used in a grounded theory study. This function helps the users to add the elements at the end of the array. Description: PEAR is a framework and repository for reusable PHP components. If you try to access it after removing it, youll get an Attribute Error. To use an instance variable an object of the class must be created. 53) What will be the output of the following program? 1. It takes a string as a parameter and converts all lowercase English character of that string to uppercase. 3) Click on environment variables: 4) Click on the new tab of user variables: 5) Write the path in the variable name: 6) Copy the path of bin folder: 7) Paste path of bin folder in the variable value: 8) Click on ok button: 9) Click on ok button The given object is printed just after the sep values. Based on the research problem, the selection of research methods by the researcher may vary. ndicates the extent to which the measurement is used. A correlation between a specific aspect of an entity and the variable being studied is either supported or rejected after an experimental research study is completed. Validity is concerned with generalizability. 21) Which of the following function displays the information about PHP and its configuration? It holds local variables and partial results, and plays a part in method invocation and return. The ternary operator (? The standard library includes the set of functions manipulating strings, files, etc. The integer value can bepositiveornegativewithout a decimal point. 17) What is the use of fopen() function in PHP? An experimental methodof research is a type of study in which the researcher speculates on the possible reasons for a previously observed result. Stepwise regression and Best subsets regression: These automated Stating the purpose and research questions in a broad way, iii. An instance variable can be declared using different access modifiers available in Java like default, private, public, and protected. Hence, from the given explanation and table, it becomes clear that qualitative research states research purpose in a broad manner collects non-numeric data, and interprets larger meanings from the findings. 32) Which of the following is the correct way to create an array in PHP? In Python, there is no restriction to declare a variable before using it in the program. As we can see that, the second print() function printed the result after 25) Which of the following function is used to unset a variable in PHP? E.g. Research in qualitative methods has historically been employed in fields such as sociology, history, and anthropology. Generalization is widely recognized as a quality criterion. The main emphasis is on groups. Java is an object-oriented programming, platform-independent, and secure programming language that makes it popular. An ex-post-facto the researcher attempts to trace an effect that has already occurred to its probable causes. Statement I:Sample sizes for qualitative research vary by technique but are generally small. Basically, this function joins all elements of an array in one string. Follow me on Twitter. Founder of PYnative.com I am a Python developer and I love to write articles to help developers. Thanks to the whole PYnative team. In other words, variable is a name which is used to store a value of any type during program execution. But if we assign m to some different value, it points to a different object with a different identity. A Global variable is a variable that is defined outside of the method (block of code). Allahabad University Group C Non-Teaching, Allahabad University Group A Non-Teaching, Allahabad University Group B Non-Teaching, NFL Junior Engineering Assistant Grade II, BPSC Asst. There are two types of data types in Java: primitive and non-primitive. (immutable such as final variables). In the above example, John, 25, 25800.60 are values that are assigned to name, age, and salary respectively. According to the American sociologist Earl Robert Babbie, research is a systematic inquiry to describe, explain, predict, and control the observed phenomenon. In short, it checks that the variable is declared and not null. A new frame is created each time a method is invoked. Instantiation: Creating an object by using the new keyword is called instantiation. Research can be broadly classified into qualitative and quantitative. Also, every Python class holds a set of special attributes. It is an act of thinking that involves drawing broad inferences from specific observations. Description: The PHP chr() function is used to generate a single byte string from a number. A PHP variable name cannot contain spaces. Every book has a unique number (identity), and that id number tells us which book is delivered to the student (object). In this section, we will discuss what is instantiation in Java, how to instantiate a class, and what are the ways to create instances or objects of the class? allow respondents to project their subjective or true opinions and beliefs onto other people or even objects. 13) Which of the following is the correct way to create a function in PHP? Techniques used for Qualitative research rely on data obtained by the researcher from first-hand observation, interviews, questionnaires, focus groups, participant-observation, recordings made in natural settings, documents, case studies, and artifacts, In these types of research, the aim is not to test a hypothesis about a broad population but to develop an initial understanding of a small or under-researched population, The goal of qualitative research is notto disprove a hypothesis, but were looking to understand the nature of a problem in detail Hencenon-probability sampling is utilized for Qualitative research. anything that varies in the context of a study other than the independent and dependent variables. It is very easy to create a simple PHP example. The configuration management process seeks to identify and track individual configuration items (CIs), documenting functional capabilities and interdependencies. Platform Independent. Let others know about it. 60) Which of the following function in PHP returns the time of sunrise of a particular day and location? Labels: Core Java Java keywords. It aims to analyze specific issues within the boundaries of a specific environment, situation, or organization. If you consider the above example, then using the __doc__ will return the doc string of that class. It includes a hypothesis, a variable that can be manipulated by the researcher, and variables that can be measured, calculated, and compared. Here, the datatype is the type of element that will be stored in the array, square bracket[] is for the size of the array, and arrayName is the name of the array. So, the program will print 1. They are broadly categorized into qualitative and quantitative research. It is the easiest way to specify string in PHP. In this tutorial, youll understand the difference between class method vs. static method vs. instance method step by step. Please mail your requirement at [emailprotected] Duration: 1 week to 2 week. Therefore, the Simulation approach, Inferential approach, andExperimental approach are theapproaches that fall under the Quantitative Approach. But, instance attributes are not specific only to the __init__() method; they can be defined elsewhere in the class. Floats are the values with the decimal point dividing the integer and the fractional parts of the number. The instance method performs a set of actions on the data/value provided by the instance variables. We should add a method to the object, so other instances dont have access to that method. The purpose of historical research is to reach insights or conclusions about past persons or occurrences. Description: In PHP, the . (E) There is greater flexibility in both the methods and research process. In a quasi-experiment, the treatment and control groups differ in other, frequently unrecognized or unknowable ways in addition to the experimental therapy they receive. If we want to reflect the change made over to the instance variable, this can be achieved with the help of this reference. So, before diving in depth, it is necessary to understand the basic structure of Java program in detail. 56) What will be the output of the following program? If we want to get the name of the datatype only as output, then we can use the__name__ attribute along with the type() function. Electrical Engineering. In Python, a string is a set of charactersrepresented in quotation marks. A - Instance variables are static variables within a class but outside any method. Experimental research helps in establishing causal relationships among different variables in asituation under controlled conditions. Now, only the reference count will be incremented. The Standard Template Library (STL) includes the set of methods manipulating a data structure. Qualitative research is descriptive in that the researcher is interested in the process, meaning, and understanding gained through words or pictures. The second advantage is that unlike constructors they are not required to create a new object each time they are invoked. The core library includes the data types, variables and literals, etc. A class can provide a public static factory method that is nothing but a static method that returns an instance of the class. In the above picture, a, b pointing to the same memory address location (i.e., 140722211837248), and c, d, e pointing to the same memory address (i.e., 140722211837568 ). In Java, if there is a local variable in a method with same name as instance variable, then the local variable hides the instance variable. So, a while loop cannot be defined without a condition. Statement I: If we are interested in the worldview of members of a certain social group, a qualitative research strategy that is sensitive to how participants interpret their social world may be preferable. Thus, the most appropriate answer isEthnography and phenomenology. Lets create the instance method update() method to modify the student age and roll number when student data details change. Please mail your requirement at [emailprotected] Duration: 1 week to 2 week. Java enum is a class that represent the group of constants. We can assign a value to the variable at that time variable is created. which are compiled into platform specific machines while Java is a write once, run anywhere language.A platform is the hardware or software environment in which a program runs. Founder of PYnative.com I am a Python developer and I love to write articles to help developers. Here, Python makes a difference between these variables that is uppercase and lowercase, so that it will create three different variables total, Total, TOTAL. Another way to instantiate a class is by calling a static factory method. But in Python, variables are dynamically typedand not subject to the data type restriction. The declaration happens automatically when we assign a value to the variable. If the keyword static is prefixed before the function name, the function is called a Establishing a research problem, Hypothesis framing, Hypothesis testing, Generalization and conclusions and Implications of result. The Standard Template Library (STL) includes the set of methods manipulating a data structure. Transcribed image text: Which of the following is true regarding subclasses? It is undertaken when a researcher wishes to trace the, Experimental research is undertaken mostly in a. In light of the above statements, choose the correct answer from the options given below. This type of research needs a subject to be studied in-depth, thus, involves the collection of large volumes of data through in-depth interviews, Focus Group discussions, observations, and various other qualitative data collection mechanisms. It involves the collection of a large amount of data and converting it into numerical form to apply statistical calculations and make conclusions. To study and obtaininformation concerning the current status of a given phenomenon. Description: The strtr() is an in-built function of PHP, which is used to replace a substring inside the other string. This mechanism is known as field hiding or, instance variable hiding. Qualitative research places the main emphasis on the researcher who narrates and interprets phenomena in terms of meanings derived from people's experiences, events, etc. Now, lets delete var1 and try to access it again. To concatenate the string, we can usethe addition(+) operator. They argue that every research should be generalizable to some extent to similar situations. Whatdata to collect (and what data to ignore), Whoto collect it from (in research, this is called, Experimental and observation based studies. Instead of creating three objects, Python creates only one object as10with references such asa,b,c. Research is a systematic inquiry towards understanding a complex social phenomenon or a process. Once we delete the variable, it will not be longer accessible and eligible for the garbage collector. PHP is an open-source, interpreted, and object-oriented scripting language that can be executed on the server-side. Description: In the given program, the variable $a is uninitialized. Ethnographers spend extensive time in the setting being studied and use observations, interviews, and other analyses to understand the nature of the culture. Description: We can declare and call user-defined functions easily. Q1. Researchis a systematic way of investigation, a process of discovering new knowledge. To retrieve a piece of string from a given string, we can use to slice operator [] or [:]. Let's see some important questions that may click in the mind. Description: The phpinfo() function gives us the information about the PHP configuration and installation in our system. Have you studied linked lists in data structure? Natural experiments are studies where the experimenter cannot manipulate the IV, so the DV is simply measured and judged as the effect of an IV. The quantitative approach emphasizes objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques. At the beginning(when we start The Python program), all books are available. First, create instance variables name and age in the Student class. All rights reserved. A local variable is a variable that is accessible inside a block of code only where it is declared.
