p p-value df degrees of freedom SS sum of squares MS mean squares With Two-Way ANOVA, you can draw Interaction Plot graphs. The number of graphs depends on Factor B, while the number of X-axis data depends on the Factor A. The Y-axis is the average value of each category. You can use the following graph analysis function after drawing a graph. • (Trace) or (TRCE) ... Trace function Pressing B or C moves the pointer on the graph in the corresponding direction. When there are multiple graphs, you can move between graphs by pressing D and A. • Graphing is available with Two-Way ANOVA only. V-Window settings are performed automatically, regardless of Setup screen settings. • Using the Trace function automatically stores the number of conditions to alpha variable A and the mean value to variable M, respectively. I ANOVA (Two-Way) S Description The nearby table shows measurement results for a metal product produced by a heat treatment process based on two treatment levels: time (A) and temperature (B). The experiments were repeated twice each under identical conditions. B (Heat Treatment Temperature) B1 B2 A (Time) A1 113 , 116 139 , 132 A2 133 , 131 126 , 122 Perform analysis of variance on the following null hypothesis, using a significance level of 5%. Ho : No change in strength due to time Ho : No change in strength due to heat treatment temperature Ho : No change in strength due to interaction of time and heat treatment temperature S Solution Use Two-Way ANOVA to test the above hypothesis. Input the above data as shown below. List1={1,1,1,1,2,2,2,2} List2={1,1,2,2,1,1,2,2} List3={113,116,139,132,133,131,126,122} 6-33
