kExample 2: Two-Way ANOVA

The values in the table below are measurement results that show how the durability of a metal product is affected by changes in heat treatment time (A) and temperature (B). Experiments were conducted twice under each condition.

 

Temperature B1

Temperature B2

Time A1

113, 116

139, 132

Time A2

133, 131

126, 122

Perform analysis of variance on the null hypotheses listed below, using a 5% level of significance.

H0 : Change in time does not affect durability.

H0 : Change in treatment temperature does not affect durability.

H0 : Changes in time and treatment temperature do not affect durability.

Use the ClassPad Two-Way ANOVA test to test the above hypotheses. Input the following measurement data into the indicated lists. This data is from the table above.

list1 (FactorList(A))

= {1,1,1,1,2,2,2,2}

list2 (FactorList(B))

= {1,1,2,2,1,1,2,2}

list3 (DependentList) = {113,116,139,132,133,131,126,122}
