ANOVA Flashcards
When did modern statistics begin and with what?
Correlation in 1886
When was the t-test developed
1908
what are the main 4 types of ANOVA
one way ANOVA
Factorial or multiway ANOVA
repeated measures ANOVA
Mixed (within and between) ANOVA
What are the factors for a one-way ANOVA
3 or more groups, 1 categorical predictor and 1 continous outcome
What are the factors for a factorial ANOVA?
2 or more groups, 2 or more predictor variables, 1 outcome
What are the factors for a repeated measures ANOVA?
1 group, 2 or more predictor variables, 1 outcome
What are the factors for a mixed ANOVA?
2 or more groups, one ore more categorical predictor variables, one outcome variable
what would one-way ANOVA appear interpret as on Jamovi
F(df1, df2)= fsk, p=
What may be needed after conducting ANOVA
post-hoc tests
What are post hoc tests
type of t-test done after ANOVA
Shows significance between groups
What are interactions
Differences in a variable is affected by differences in another
What assumptions are made when conducting an ANOVA
there is normal distribution in residuals
observations are independent
variance of different groups or conditions are equal
what assumption is made for a repeated measures ANOVA
differences between levels of a variable have equal variance
should click spericity in jamovi
what does the general linear model assume
residuals are normally distributed
different statistical tests combine linearly
what is the purpose of the general linear model
assess strengths and directions of relationships and differences
assess strengths of interactions and manipulations
