SSb
3. What does the 'mean' in 'mean square' indicate
An average measure of variance
4. What does the one way in one way ANOVA indicate
the fact that there is just one independent variable
5. What is scale of the independent variable in ANOVA
nominal
6. What is scale of the independent variable in ANOVA
nominal
7. In an ANOVA what symbol is used to indicate the number of groups
k
8. What of the following is true in an ANOVA

9. The dependent variable in ANOVA must be at least of what scale
nominal
10. Which statistic is the ratio of treatment variance to error variance
F
11. what statistic measures within group variability in a z-score problem
the standard error of the mean

the standard deviation
13. what value of z includes the middel 95% of thedistribution of sample means
+/- 1.96
14. when comparing the distribution of sample means to a distribution of individual scores, which is accurate
omega does not equal omega means, mu equals mu means
15. what is the scale of the data when students are identified according to major
ratio
16. which measure of central tendency is most affected by outliers
mean
17. if data have positive skew, what's the order of the central tendency measures from left to right
mode, median, mean
18. I have scores of 2, 3, 3, 4, 5, 6, 6, 6, 7. which value is the median
5
19. which is the only statistic that can be calculated for nominal scale data
the mode
20. increasing the number of scores near the mean has which effect
the standard deviation will decrease
21. the vertical height of the line in a frequency distribution indicates which
the number of cases of a particular score
22. a distribution has s=3.0 and R=24. Which is accurate?
The distribution is leptokurtic
23. which statistic measures within group variability in a z score problem
the standard error of the mean
24. which value measures sample variability in the distribution of the sample means
the standard error of the mean omega means
25. what is the lowest value omega squared can have
0
26. SEm is a statistic. what is the equivalent parameter
omega means
27. failing to reject the null hypothesis is the same as acknowledging which
differences are likely just random
28. there are many t distributions. each is defined by which
degrees of freedom
29. which statistics is described as 'an estimate of pooled variance'?
the standard error of difference
30. which of the following estimates the standard deviation of all 'difference' scores
SEd
31. the standard error of the mean measures variability from what sources
the variability within one group
32. which of the following defines alpha (type 1) error
rejecting the null when there is no difference
33. which of the following will increase the value of t in an independent t-test
rejecting the null when there is no difference
34. if you test at p=.05 and reject the null hypothesis, what's the probability of a error
.05
35. if you test at p=.05 and reject the null hypothesis, what's the probability of B error
0
36. the one sample t-test answers which question
does the sample belong to the described population
37. the point of calculating an effect size is which
to determine the practical importance of the result
38. why do critical values decrease as degrees of freedom increase
because the sample becomes more normal as df increases
39. the confidence interval indicates which
the range within which the true value is likely to occur
