Effect Sizes
We get this information from effect size, but not from p-value.
What is the magnitude of the effect?
The relationship between F and t when running an ANOVA with two levels of the IV.
What is f = t squared?
In regression we use this term instead of dependent variable.
What is outcome?
This assumption is very important but must be taken care of in the design of the experiment
We check these two things if we violate normality
What is sample size and histogram?
The effect size we use when conducting t-tests or any pairwise comparisons.
What is cohen's d?
If we run a repeated measures ANOVA with two levels of the IV, we could also run this analysis instead to get the same p-value
What is dependent samples t-test?
When checking assumptions in Jamovi, a small p value indicates this.
What is violation?
What are p-value and # of levels of the IV?
The interpretation of partial eta squared.
What is the variance in the DV explained by the IV?
This ANOVA includes both between and within subjects factors.
What is mixed design ANOVA?
This is the regression equation
what is y prime = b(x) +a?
To determine statistical significance we want the obtained test value (e.g., t, f, etc) to be ____ compared to the critical value.
If we violated HOV, we run this kind of t-test instead
What is separate variances (Welch's)?
This effect size has the same interpretation as partial eta squared.
What is r squared?
What is within subjects?
This is why we use adjusted r squared
What is to correct for the inflation in the r squared value?
This error is inflated with each additional analyses in an experiment.
What is type 1 error?
In cases where it may be difficult to obtain a large sample size, we use this kind of design where possible.
What is repeated measures/within subjects?
What is standard deviation units?
This is how we should approach interpretation of main effects when the interaction effect is significant.
What is with caution?
What is for every one additional hour spent study, mastery review scores increase by 7?
The theoretical curve formed if we were to infinitely sample from the population.
What is a sampling distribution?
IF you don't have any notes with you, then this is the formula for SS within that you could recall from memory :)
What is the sum of each groups variance multiplied by the sample size of each group minus 1 ?
