One Way ANOVA Flashcards
analysis of variance and a statistical tool to calculate if there are significant
difference between the means of three or more
populations
ANOVA
what is the parametric counterpart of ANOVA
kruskal wallis test
this is to determine how close and how far the means are from each other
ANOVA
where does the ANOVA depend? independent or dependent
independent variable
deals with exact data or variables of a subset, very tedious and involves computation
parametric
designates ranking for the variables, no computation involved
non parametric
comparison of three population groups and has only one independent variable
one way anova
comparison of three population group and has two variable
two way anova
has three or more population group
multiple way anova
if alternative hypothesis is accepted (null rejected), what computation needs to be performed
post hoc test
if the value is greater than the critical value
accept H1 (post hoc)
if the value is less than critical value
accept H0 (no post hoc)
this is the area where we decide if we accept or reject null hypothesis
critical value
df(b) = k - 1
k stands for
number of experimental groups
df(w) = N - k
N stands for
number of participants in the study
