This is a research project created by me for class. I do not have to solve the problem or provide information about the students. This is an exercise to see if I comprehend each statistical procedure that was studied. I wanted to use the paired t-test to compare before and after scores, but we did not study the paired t-test. I need to change the question to fit a different statistical test.

What type of research can I use to solve this problem? Does instructional design and technology change the behavior of early childhood students of drug-addicted mothers?

We have studied Independent Samples T-Test, One-Sample T-Test, Chi-Square, ANOVA, Pearson Product-Moment Correlation, and Bivariate Regression.

The research question can be divided into female and male, 'yes' and 'no' or multiple before and after scores. We have not studied paired t-tests. Please give an example of a research question and a null hypothesis so that my wording will be correct.

Research Question:Does instructional design and technology change the behavior of early childhood students of drug-addicted mothers?

Null Hypothesis:Instructional design and technology have no statistical impact on the behavior of the population of early childhood drug-addicted students

Independent variable:Instructional design and technology interventions

Dependent variable: 'Yes' or 'No' (Female or male) (before and after scores)

Instrument (Scale): Edmond's Nonclinical Early Childhood Behavior Measurement Test

Participants: Four selected toddlers in Hayes Enrichment School as identified by the Individuals with Disabilities Education and Improvement Act of 2004.

Statistical Test:
