What is Analysis of Variance (ANOVA)
100
The F ratio for rANOVA is ____ over ____
What is MSbetween/MSerror
100
is a statistical technique which describes the direction and degree of the relationship between two variables.
What is correlation
100
Refers to the number of treatments in an experiment
What is K
100
high scores on one variable are associated with lower scores on the other variable, or vice versa (e.g. calories consumed amount of weight loss)
What is negative correlation
200
In one-way ANOVA there are __ independent variable(s) and __ dependent variable(s)
What is 1 and 1
200
The total variability for rANOVA is divided among
What is between, within/subjects, and error
200
is a joint distribution of two variables; scores are paired
What is bivariate distribution
200
___ is the variance in ANOVA. It is found by dividing Sum of squares by degrees of freedom.
What is Mean Square
200
For one-way ANOVA, you need to know two degrees of freedom what are they and how are they written.
What is degrees of freedom between, within. df(between,within/error)
300
The null hypothesis for a one-way ANOVA argues
What is all three (or more) treatments are equal
300
Name an advantage of rANOVA over independent samples ANOVA
What is cheaper, faster, or discards variability between subjects.
300
is a technique which: draws the line that best fits the data, predicts a person’s score on one variable when you know that person’s score on a second, related variable
What is regression
300
higher numbers on one variable tend to be associated with higher numbers on the other variable; height and weight
What is positive correlation
300
After finding a significant F value for an ANOVA, what is the next step?
What is Tukey's HSD
400
The sampling distribution used in ANOVA
What is F distribution
400
Name a disadvantage of rANOVA
What is carryover effects
400
Equation that predicts values of Y for specific values of X
What is regression equation
400
dependability or consistency of a measure. The correlation coefficient is used to determine the reliability or agreement between administrations of tests.
What is reliability
400
If the null hypothesis is true, the F ratio should equal to ___
What is one
500
In one-way ANOVA the variability is divided among which two sources
What is between treatments and within treatments/error
500
the symbol Nt refers to
What is number of scores within a given
500
In the regression formula, this is the slope of the regression line
What is b
500
This type of relationship yields a low correlation coefficient. It is a nonlinear relationship in which scores begin to demonstrate a positive correlation, but then drop off at a certain point (e.g. the relationship between anxiety and text performance).
What is curvilinear relationship
500
After finding significant differences using Tukey's HSD test, what is your next step?
