One Way Anova Test Example. Let us understand one way anova with an example. The pieces of metal were cured.
A tukey post hoc test revealed significant pairwise differences between fertilizer types 3 and 2 with an average difference of 0 42 bushels acre p 0 05 and between fertilizer types 3 and 1 with an average difference of 0 59 bushels acre p 0 01. Each plant is treated with one out of three available treatments to enhance the weight of each plant. At least one population mean is different from the rest.
The below mentioned formula represents one way anova test statistics.
In order to test for the equality of means and to assess the differences between pairs of means the analyst uses one way anova with multiple comparisons. Reporting the results of a one way anova we found a statistically significant difference in average crop yield according to fertilizer type f 2 9 073 p 0 001. A project was taken to reduce the processing time. At least one population mean is different from the rest.
