What Test?
This test is used to determine whether or not there is a statistically significant difference between the means of three or more groups in which the same subjects show up in each group
What is Repeated Measures ANOVA?
These are the three types of t tests.
What are independent/unpaired, paired, and one sample t test?
This is the purpose of a residual plot?
What is showing the difference between the observed value and the fitted values?
This test is used to compare the means of two samples when each individual in one sample also appears in the other sample.
What is a paired t-test?
This is is a value used to represent the extent to which a null hypothesis is false.
What is an effect size?
Residual Diagnostics test for all of the following EXCEPT:
- normal distribution
- mean of 1
- homoscedasticity
What is mean of 1?
This type of test is used to compare the means of two samples when each individual in one sample is independent of every individual in the other sample.
What is an individual samples t-test?
This is a ratio between the difference between two groups and the difference within the groups.
What is a T score?
Residual diagnostics are represented with this type of graph.
What is a scatter plot?
Grace wants to find out whether two study methods lead to different mean quiz scores. She decides to have one group of students use Jeopardy review then take a quiz. She then has the same group use Quizlet for the same duration and take an equally difficult quiz. She is using this type of test.
What is paired t-test?
This is the range of values you expect your estimate to fall between if you redo your test.
What is the confidence interval?
This occurs when the residuals are not independent of each other.
What is auto-correlation?
Grace wants to see how students' sleep schedule is affected throughout the semester. To test this, she has her class report their average sleep hours from a week in the beginning of the semester, during midterms, and during finals. This is the type of test she will use to evaluate her data.
What is repeated measures ANOVA?
If your confidence interval excludes your null hypothesis value and the p-value is smaller than the significance level, you must do this.
What is reject the null hypothesis?
This is a problem because it indicates that the residuals are drawn from a population with constant variance.
What is heteroscedasticity?
