Explanation / Answer

Ans 5 option A - 20

The individual treatments are called factors.

The treatment levels within a factor are called levels.

A 2 x 2 factor experiment with two factors and two levels for each factor is denoted as a 22 factorial experiment.

In the factorial approach, the investigator compares all treatments that can be formed by combining the levels of the different factors. Factorial experimentation is highly efficient, because every observation supplies information about all the factors included in the experiment. Also factorial experimentation is a systematic method of investigating the relationships between the effects of different factors.

Ans 6 option D

Two population testing in statistics can be performed using an ANOVA (Analysis of Variance) test. While the t-test compares means, ANOVA compares the variance between the populations. A Two way ANOVA in Excel without replication can compare a group of individuals performing more than one task. For example, you could compare students’ scores across a battery of tests.
