For the ANOVA method, select all choices below that are assumptions of this method.
a, b, c, d, e, f
For the ANOVA table, select all choices that is a column heading in the ANOVA table.
a, c, b, d
Given the information shown below from a study of the number of births by season, please match each of the following questions with their appropriate answers.
c, d, b, a
Given the information shown below from a study of the number of births per weekday, please match each of the following questions with their appropriate answers.
a
In the ANOVA table below, are all the degrees of freedom correct if there are three (3) populations and ten (10) data values from each population?
a, b
In the ANOVA table below, match up the values of the two Mean Squares.
b, a
In the ANOVA table below, match up the values of the two Sum of Squares.
a
In the ANOVA table below, should the populations means be considered equal?
d
In the ANOVA table below, should the populations variances be considered equal? a) No, because there are no sample variances In the ANOVA table. b) No, because the p-value (<0.0001) is less than alpha (0.05). c) No , because the MS(DAY) (3,564,717) does not equal MS(Error) (193,771). d) Unknown, because the ANOVA table tests for means, not for variances.
