What is "just one penny."
300
Used to ensure that different groups are equivalent, and that there is no systematic bias in how subjects are assigned to groups
What is random assignment

A researcher compares two 3rd grade classrooms on reading achievement. She uses a new reading instruction method with only one class. This type of design is a(n)
What is a quazi-experimental design
300
The type of single subject design used when more than one individual is under study
What is multiple baseline deisgn
300
The best method for predicting a DV from multiple IVs.
What is multiple regression
400
How different variables are organized or identified in a meta analysis so that they can be compared
What is coding
400
The overall effect of an independent variable
What is a main effect

A researcher thinks that gender has an impact on math achievement. He gives math tests to all students in the school, and finds differences between boys and girls on math achievement. This design is a(n)
What is a causal-comparative design
400
A common name for the baseline/treatment/baseline/treatment design. Hint: this is not the name of a famous 1970's singing group from Sweden.
What is ABAB
400
A researcher finds a simple correlation, r = .25, between achievement motivation and a child's time spent with parents between the ages of 2 and 18. The proportion of variance in achievement motivation accounted for by time spent with parents is
What is .0625 (or what is 1/16)
500
What Hyde, et al found in their 2008 reanalysis of the differences between males and females on mathematics achievement
What is no difference (d = 0).
500
When a design has both within and between groups factors, this is a(n)
What is a mixed design
500
Results from single subjects designs can be generalized to
What is the individual under study only. (unless you replicate it with other individuals)

A researcher knows that the simple correlation between age and years of education is positive and strong; the simple correlation between years of education and amount of income is strong and positive; and the relationship between years of education and interest in fishing is nonexistent (r = 0). Based on this information, if the researcher were to perform a multiple regression predicting years of education from age, amount of income, and interest in fishing, what contribution to R-squared would you anticipate interest in fishing would provide?
What is zero
