If data is not a matched-pair test, what is it?
Independent Test
100
Name all seven tests.
Wilcoxon Signed-Rank Test for a Population Median Wilcoxon Signed-Rank Test for a Matched Pair Wilcoxon Rank-Sum Test for Independent Samples Kruskal-Wallis Test Spearman Rank Correlation Test Sign Test Wald-Wolfowitz Runs Test

What does SPSS stand for?
Statistical Package for the Social Sciences
100
What does MDA stand for?
Multidiscriminant Analysis
100
What does R^2 explain?
The amount of variation in the response variable that is due to the changes in the explanatory variable.
200
What is mD?
The median of the population of paired differences (xi - yi)
200
Which test uses the correlation coefficient in the hypotheses?
Spearman rank correlation test
200
What are the two views?
Data and variable
200
What does discriminate mean?
To classify
200
What is standard deviation?
A measure of the variation of the data (how spread out the data is)
300
How is the test statistic for the Wilcoxon Rank-Sum Test for Independent Samples determined?
W is determined by the sum of the ranks from the smaller of the two samples.
300
How is each matched pair scored in the sign test?
"+" when the first value is better than the second "-" when the first value is worse than the second "0" for all ties
300
What is the difference between SPO and SAV?
SAV saves data view and variable view while SPO saves the output
300
What does Excel with add-in use to measure?
Mahalanobis distance
300
What is the standard error of the estimate?
Measure of the average distance the points are from the line of best fit
400
The Wald-Wolfowitz runs test is used to determine what?
If the elements of a sequence appear in a random order.
400
In the majority of the tests, when n < 10, use what? When n >= 10, use what?
Use the table in the back of the book Assume normally distributed and use the formulas
400
Compare chart builder and legacy dialog.
Chart builder is the new way of creating charts. It takes a drag and drop approach. Legacy is the old way of creating charts.
400
Why was Excel with add-in a better predictor than SPSS?
Chance
400
What is MSR?
Regression Mean Squared: average distance between yhat and the mean
500
Which test does not rely on n < 10 and n >= 10?
Kruskal-Wallis test
500
Which test has to have each n = 10?
Wald-Wolfowitz runs test
500
When was SPSS created?
1968
500
How is the discriminate score calculated?
By plugging the x variable values into the regression equation.
500
What is SST?
Total Sum of Squares: total squared variation between the data points and the mean.
