Exam 13: Nonparametric Statistics

Six second grade students tried tossing a ball into a basket ten times each.Their teacher then suggested a different way of tossing the ball, and the six students tried again.The Number of successful tosses, before and after the teacher's added instruction, are shown Below. Ignoring the differences of 0, the negative rank sum is:

When the assumptions for the ANOVA test that populations are normally distributed and population variances are equal cannot be met, the __________ test can be used to compare three or more means.

The smaller number of + or - signs is used in the z Test static in the Sign Test for samples of 26 or bigger

Two students were asked to rate six different television shows on a scale from 0 to 10.The data are shown in the following table: What is the Spearman Rank Correlation Coefficient for this set of data?

Many nonparametric tests involve ____________, or positioning of the data values in a data array according to a scale. ________________________________________

If a researcher is using the sign test and has 12 positive signs, 18 negative signs, and 4 zeros, what is the test value?

The data collected for studying whether or not there is a difference between the number of hours men and women watch television is summarized below.To compute the test value, the data from both samples Should be combined, arranged in order, and ranked according to each group. Calculate the , and z-test value for the Wilcoxon rank sum test started in problem 32 and Continued in problem 37.
