2) TRUE OR FALSE: The goal of descriptive statistics is solely to summarize, and organize data.

3) TRUE OR FALSE: Inferential statistics involves inferring something about a sample from population data.

4) TRUE OR FALSE: In a study entitled the relationship between study time and grades, study time is the predictor variable.

5) TRUE OR FALSE: Statistical methods that use sample data to make statements about populations are called inferential statistics.

6) TRUE OR FALSE: The IV is the variable that is the measured in an experiment.

7) Which is the manipulated variable in an experiment?

b.) Explanatory variable

c.) DV

d.) Predictor variable

Answer 1

1. Independent and dependent variable are associated with an experiment so (a) is correct choice.

2. True because descriptive statistics deals with graphs and summary variable alike mean and standard deviation.

3.   False because in inferential statistics we find results for population from the sample data but above in question it is given vice- vesa.

4. True because here study time is independent variable through which we can predict about the dependent variable grades, so study time is a predictor variable.
