Question

Would the following experiment use a block design?

An experiment was conducted to determine if experience has an effect on the time it takes for mice to run a maze. Four treatment groups, consisting of mice having been trained on the maze one, two, three and four times were run through the maze and their times recorded. Three mice were originally assigned to each group, but it was discovered that some lab assistants, in an attempt to win a bet, gave one mouse a stimulant and another mouse a sedative. These mice were removed from the analysis.

Answer 1

In this problem we need to conduct a single factor ANOVA. You can use a block design.
