Question 1

What is a hypothesis?
A)a statement that the researcher wants to test through the data collected in a study.
B)a research question the results will answer.
C)a theory that underpins the study.
D)a statistical method for calculating the extent to which the results could have happened by chance.

Accepted Answer

A hypothesis is essentially a statement or prediction that a researcher aims to test through the collection and analysis of data within a study. It is not a question, theory, or statistical method itself, but rather a specific assertion about the relationship between variables that the study seeks to confirm or refute.

Question 2

The process of quantifying data is referred to as _________.
A)typology
B)diagramming
C)enumeration
D)coding

Accepted Answer

Enumeration is the process of quantifying data, which involves counting or assigning numbers to data in order to analyze it quantitatively.

Question 3

An advantage of using computer programs for qualitative data is that they _______.
A)can reduce time required to analyse data (i.e., after the data are transcribed)
B)help in storing and organising data
C)make many procedures available that are rarely done by hand due to time constraints
D)all of the above

Accepted Answer

Computer programs for qualitative data analysis offer several advantages, including reducing the time required to analyze data once it's transcribed, aiding in the storage and organization of data, and making available many procedures that are impractical to do by hand due to time constraints.

Question 4

Boolean operators are words that are used to create logical combinations.

Accepted Answer

Boolean operators, such as AND, OR, and NOT, are used in search engines, databases, and programming to create logical combinations and refine search queries or conditions.

Question 5

__________ are the basic building blocks of qualitative data.
A)categories
B)units
C)individuals
D)none of the above

Accepted Answer

Categories are the basic building blocks of qualitative data, as they allow researchers to organize, interpret, and analyze the data by grouping it into meaningful classes or groups.

Question 6

This is the process of transforming qualitative research data from written interviews or field notes into typed text.
A)segmenting
B)coding
C)transcription
D)mnemoning

Accepted Answer

Transcription is the correct process where qualitative research data, such as from interviews or field notes, is converted into typed text for analysis.

Question 7

A challenge of qualitative data analysis is that it often includes data that are unwieldy and complex; it is a major challenge to make sense of the large pool of data.

Accepted Answer

Qualitative data analysis involves interpreting large amounts of non-numerical data, such as interview transcripts, observations, and texts, which can be complex and difficult to systematically organize and analyze.

Question 8

Hypothesis testing and estimation are both types of descriptive statistics.

Accepted Answer

Hypothesis testing and estimation are types of inferential statistics, which are used to make inferences or predictions about a population based on a sample. Descriptive statistics, on the other hand, are used to describe the basic features of the data in a study.

Question 9

A set of data organised in a participants(rows)-byvariables( columns) format is known as a "data set."

Accepted Answer

A data set organized in a participants (rows) by variables (columns) format is a common way to structure data for analysis, allowing for easy access to and manipulation of the information.

Question 10

___________ are used when you want to visually examine the relationship between two quantitative variables.
A)bar graphs
B)pie graphs
C)line graphs
D)scatterplots

Accepted Answer

Scatterplots are specifically designed to show the relationship between two quantitative variables, allowing for the visualization of how one variable is affected by the other.

Question 11

A statement made about a population for testing purpose is called?
A)statistic
B)hypothesis
C)level of significance
D)test-statistic

Accepted Answer

A hypothesis is a statement made about a population for testing purposes, which can then be tested through statistical methods to determine its validity.

Question 12

If the assumed hypothesis is tested for rejection considering it to be true is called?
A)null hypothesis
B)statistical hypothesis
C)simple hypothesis
D)composite hypothesis

Accepted Answer

The null hypothesis is the hypothesis that is assumed to be true and is tested for rejection in statistical analysis. It represents a statement of no effect or no difference and is the starting point for many statistical tests.

Question 13

If the null hypothesis is false then which of the following is accepted?
A)null hypothesis
B)positive hypothesis
C)negative hypothesis
D)alternative hypothesis.

Accepted Answer

When the null hypothesis is false, the alternative hypothesis is accepted. The alternative hypothesis proposes a different outcome or effect than the null hypothesis, which typically states there is no effect or difference.

Question 14

Alternative Hypothesis is also called as?
A)composite hypothesis
B)research hypothesis
C)simple hypothesis
D)null hypothesis

Accepted Answer

The alternative hypothesis is also known as the research hypothesis. It is the hypothesis that suggests there is an effect or a difference, and it is what the research aims to support or prove.
