Two different workbooks and two distinct teaching machines were to be evaluated on their effectiveness in teaching the concept of multiplication. A fourth grade class of 24 subjects was randomly assigned to 4 groups and each group in turn was randomly assigned to a teaching method. A test was given and the number of errors was recorded. This problem uses the Kruskal-Wallis H test to see if the number of errors differs from one teaching method to another. What is the value of H in this problem?
______________
Find the rejection region for = 0.05.
Reject if H ______________
Conclude: ______________
There is ______________ evidence at = 0.05 to say that the number of errors differs from one teaching method to another.
What is the p-value for this test?
______________
