The primary reason for conducting a two-way ANOVA instead of a one-way ANOVA is to: |
||||||||||

. |

Answer #1

Option B is the correct answer

Option B

Because in ANOVA hypothesis it can be in a manner which is to be applied if you have an expanding number of two loose gatherings, a downright independent variable with as a minimum 2 groupings, and a generally conveyed meantime ward variable. The t test can be utilized in comparable situations apart from absolute facts with 2 levels.

The test measurement inside the t-check is referred to as the t-estimation. The t-test takes a gander at the t-estimation, t-appointment.

ANOVA to test your hypothesis. In a Word document or PDF answer the
questions below. Label your submission clearly so it's easy to
figure out which sections you're answering. 1. In a couple
sentences, describe the study design and how the independent and
dependent variables were measured (mentioning the scale of
measurement: nominal, ordinal, interval, ratio). 2. In SPSS, create
a set of data that has at least 10...
