What is the Open Science Framework?

Using the framework of Crocker and Algina for test construction, briefly list the key steps you would follow if you were to develop a 25-item job satisfaction measure for teachers. 

A researcher compared the science exam scores for 100 students who received 2 weeks of Direct Instruction to the science exam scores for 100 students who received 2 weeks of Discovery Learning Instruction.  What type of hypothesis would be the following: There is a difference in the population mean science scores for the Direct Instruction and Discovery Learning Instruction conditions.

The following linear regression equation was determined from 100 students who reported how long they studied for the final exam, where X is the number of hours that students studied for the final exam, and Y is the final exam score Y = 85 + 2 (X) How many dependent variables are represented by this equation?

A researcher compared the science exam scores for 100 students who received 2 weeks of Direct Instruction to the science exam scores for 100 students who received 2 weeks of Discovery Learning Instruction.  The research was concerned that the comparison might not be fair because the groups might have differed in their science knowledge even before the instruction was implemented. List 1 way the researcher could control for this extraneous variable of prior science knowledge.

What is statistical power?

In a qualitative research study where interview data were collected, what is involved in open coding?

List 1 major element of focus group interviews.

How many dependent variables are in a 3-Way ANOVA?

Random assignment of participants to the conditions of a manipulated independent variable (e.g., treatment vs. control) is designed to enhance which type of validity?
