Exam 4 Review

When data is in the form of frequencies, this prevents our distribution from being normally distributed.

With a strong correlation, we can assume that X causes Y.

In the regression equation, Y' = a + bx, b will tell us the direction, but not the strength.

In a 2x2 factorial design, how many conditions are there?

When writing up the results for a Chi-square test, the groups' frequencies should be stated in __________ order.

For regression, Y' represents the ___________ in the equation Y' = a + bx.

When the effect of one factor changes based on the level of another factor, this is called a(n) ____________.

__________ is the concept that we should accept the simplest answer, as opposed to the kitchen-sink approach.

A correlation coefficient of -0.9 will be __________

Which of the following is a nonparametric statistical analysis method?

When the value of b (beta) that we calculate is the predicted change in the original units of the outcome, this is a(n)

In a 2x3 factorial design, how many factors are there?

A correlation coefficient's (r) sign tells us the ___________ of the change.

An individual effect of a factor within a factorial ANOVA that ignores the other factors is called a(n) ____________.

A ___________ is the difference between the actual Y' score and what the regression line predicted it would be.

In a Jamovi output for a factorial ANOVA, if the p-value is ___________ the alpha (.05), there is no main effect.

For correlation, the effect size ___________ depend on our sample size.

For correlation, degrees of freedom = ___________.

Based on the graph, is there an interaction between these factors?

In a Chi-square test, if there is no difference between the frequencies, X² will be _________.
