1. Introduction, Data Literacy, and Variables

Question 1

What are the six steps of empirical research in quantitative studies?

Answer 1

Research Question, Literature Review, Research Design, Data Collection, Data Analysis, Reporting Results

Question 2

What is the primary focus of quantitative data?

Answer 2

Measuring ‘how many’ or ‘how much’ with numerical values.

Question 3

What is the primary focus of qualitative data?

Answer 3

Exploring ‘how’ and ‘why’ with textual or descriptive data.

Question 4

Why is quantitative research important in psychology?

Answer 4

It supports evidence-based practice, such as assessing therapy effectiveness and analyzing mental health trends.

Question 5

Define data literacy in psychology.

Answer 5

The ability to read, understand, evaluate, and make decisions based on data.

Question 6

What are the four key skills of data literacy?

Answer 6

Reading data (interpreting graphs and statistics), Critical thinking (identifying biases and limitations), Decision-making (using data to guide actions), Communicating insights (explaining findings effectively)

Question 7

What are practical applications of data literacy in psychology?

Answer 7

Understanding survey results, interpreting behavioral study patterns, and evaluating psychological assessments.

Question 8

What is a variable in research?

Answer 8

A characteristic or property that can take on different values.

Question 9

What are the three main types of variables?

Answer 9

Categorical Variables, Numerical Variables, continuous vs discrete

Question 10

What are the subtypes of categorical variables?

Answer 10

Nominal: No inherent order (e.g., gender, ethnicity). Ordinal: Ordered categories without equal intervals (e.g., education levels).

Question 11

What are the subtypes of numerical variables?

Answer 11

Interval: Equal intervals but no true zero (e.g., temperature in Celsius). Ratio: Equal intervals with a true zero (e.g., height, weight).

Question 12

What is the difference between continuous and discrete variables?

Answer 12

Continuous: Can take any value within a range (e.g., income). Discrete: Takes distinct, countable values (e.g., number of children).

Question 13

What is an operational definition in research?

Answer 13

Assigning specific measurement criteria to abstract concepts to make them measurable.

Question 14

Define independent and dependent variables.

Answer 14

Independent Variable (IV): Manipulated or controlled by the researcher (e.g., study time). Dependent Variable (DV): Measured outcome influenced by the IV (e.g., test scores).

Question 15

What does it mean for variables to be associated?

Answer 15

If one variable predicts another, they are considered associated.

Question 16

Give an example of an independent and dependent variable relationship.

Answer 16

Political affiliation (IV) might predict voting behavior (DV).

Question 17

What are the two main types of statistical methods?

Answer 17

Descriptive Statistics (summarizes observed data), Inferential Statistics (generalizes findings to a population)

Question 18

What are some common data analysis tools used in psychology?

Answer 18

SPSS (for statistical analysis), Excel (for organizing and analyzing data)

Question 19

What are best practices for effective data analysis?

Answer 19

Cumulative learning for retention, Critical engagement with methodologies, Focusing on result interpretation over complex calculations

Question 20

How does research design impact a study?

Answer 20

It determines how participants are selected, what tools are used, and how data is collected and analyzed.

Question 21

What are examples of how quantitative research supports psychology?

Answer 21

Assessing therapy effectiveness
Analyzing survey trends in mental health
Evaluating intervention outcomes

Question 22

What is the importance of data visualization in research?

Answer 22

It simplifies complex data through graphs, charts, and tables to aid interpretation and communication.

Question 23

What are examples of data visualization tools?

Answer 23

Bar charts
Histograms
Box plots

Question 24

What are the key criteria for a good operational definition?

Answer 24

Clarity and precision
Measurability
Reproducibility

Question 25

What are the ethical considerations when collecting data?

Answer 25

Informed consent
Confidentiality
Data integrity and accuracy

Question 26

What challenges can arise when working with survey data?

Answer 26

Response bias
Missing data
Sampling errors

Question 27

What is the significance of making data-driven decisions in psychology?

Answer 27

It ensures interventions and policies are based on objective evidence rather than intuition.

Question 28

How do researchers ensure data validity and reliability?

Answer 28

By using standardized measurement tools and consistent data collection methods.

Question 29

What is the role of replication in quantitative research?

Answer 29

To verify results and ensure findings are reliable and applicable across different contexts.
