Types of Data Assessment

What is the difference between categorical and numerical data?

• Categorical data is objective, while numerical data is subjective.

• Categorical data is quantitative, while numerical data is qualitative.

• Categorical data is continuous, while numerical data is discrete.

• Categorical data is qualitative, while numerical data is quantitative.

Identify an example of primary data source.

• Conducting a survey

• Analyzing secondary data

• Reviewing literature

• Interviewing experts

Explain the concept of discrete data.

• Discrete data is data that is uncountable.

• Discrete data is data that can only take specific values and is typically countable and finite.

• Discrete data is data that can take any value within a range.

• Discrete data is data that is always continuous.

How is time series data different from cross-sectional data?

• Time series data is only qualitative, while cross-sectional data is only quantitative.

• Time series data is collected for a single point in time, while cross-sectional data is collected over time.

• Time series data is used for predicting future events, while cross-sectional data is used for historical analysis.

• Time series data is collected over time, while cross-sectional data is collected at a specific point in time.

Define secondary data source.

• Data collected for the primary purpose

• Data that has been previously collected by someone else or for a different purpose.

• Data obtained from a reliable source

• Data gathered directly by the researcher

Differentiate between continuous and discrete data.

• Continuous data is categorical, discrete data is numerical

• Continuous data is qualitative, discrete data is quantitative

• Continuous data can only take specific values, discrete data can be measured

• Continuous data can be measured and take any value within a range, while discrete data can only take specific values and is usually counted.

What is panel data and how is it different from time series and cross-sectional data?

• Panel data differs from time series data by including multiple individuals or entities, and it differs from cross-sectional data by including observations over time.

• Panel data is the same as time series data

• Panel data only includes cross-sectional data

• Panel data only includes time series data

Give an example of numerical data.

• 175 cm

• 123 apples

• 15.7 kg

• green

Identify a primary data source in a research study.

• Surveys, interviews, experiments, or observations

• Case studies, literature reviews, secondary data analysis

• Focus groups, content analysis, meta-analysis

• Questionnaires, case studies, content analysis

Explain the concept of secondary data.

• Secondary data is pre-existing data that is used by researchers for their own purposes.

• Secondary data is data collected firsthand by researchers.

• Secondary data is only used in qualitative research.

• Secondary data is always more reliable than primary data.
