Oneway ANOVA >Singlefactor analysis of variance.
In psychology, OneWay ANOVA (Analysis of Variance) is a statistical method used to test for differences between three or more groups on a single variable. It is used to determine whether there is a significant difference between the means of two or more groups.
Here are some examples of how OneWay ANOVA might be used in psychology:

Depression levels: A psychologist might use OneWay ANOVA to compare the levels of depression in three different groups of individuals: those receiving therapy, those taking medication, and those receiving a placebo. The psychologist would measure depression levels using a standard questionnaire and then compare the mean scores for each group to determine whether there is a significant difference between them.

Learning styles: A researcher might use OneWay ANOVA to investigate whether there are differences in learning styles among three different groups of students: visual learners, auditory learners, and kinesthetic learners. The researcher would use a standard measure of learning style preference and compare the mean scores for each group to determine whether there is a significant difference between them.

Personality traits: A psychologist might use OneWay ANOVA to compare the levels of a particular personality trait, such as extraversion, in three different age groups: teenagers, young adults, and older adults. The psychologist would measure extraversion levels using a standard personality questionnaire and compare the mean scores for each group to determine whether there is a significant difference between them.

Perceived stress: A researcher might use OneWay ANOVA to investigate whether there are differences in perceived stress levels among three different groups of workers: fulltime employees, parttime employees, and contract workers. The researcher would use a standard measure of perceived stress and compare the mean scores for each group to determine whether there is a significant difference between them.
