100
You want to compare your sample of Texan gerbils’ maze running ability to that of the whole population. You would use this test.
What is a one-sample t?
100
The highest and lowest number possibilities of the correlation coefficient.
What is 1 and -1?
100
Your group membership variable, or what the researcher manipulates.
What is an independent variable?
100
The two numbers divided to get the mean square of one of the factors.
What is sum of squares between and sum of squares error?
100
A graph involving the first digit of each number at the beginning of each row, and the second digit of each number listed in order after it.
What is a stem and leaf plot?
200
You want to know if the frequency of gerbils who died while they were given an overdose of baby aspirin was significantly different from the frequency of gerbils who died while they were given an overdose of adult aspirin. You would use this test.
What is a chi-square test?
200
What you cannot infer from a correlation.
What is cause?
200
This hypothesis states that there is no difference between groups.
What is the null hypothesis?
200
a-1.
What is the degrees of freedom between groups?
200
I use this type of frequency graph is my data is continuous.
What is a histogram?
300
You are comparing gerbils whose water was laced with either Tylenol, Valium, or a placebo. You would use this test.
What is ANOVA?
300
.4 is this type of correlation (magnitude and direction).
What is moderate positive?
300
What we do to our null hypothesis when we find significance.
What is reject?
300
The place you find the error in the F-ratio.
What is the denominator?
300
The graph that looks like a big shape that's been colored in.
What is a frequency polygon?
400
You want to compare the same gerbils’ maze running ability after taking first Prozac and then Xanex.
What is a dependent t-test?
400
As variable A increases, variable B decreases.
What is a negative correlation?
400
The variable that you are measuring.
What is the dependent variable?
400
A factorial ANOVA involves more than one of these.
What is an independent variable OR a factor?
400
Your first interval has 3 people in it. Your second has 3. Your third has 6. Your fourth has 2. What is the cumulative frequency at your third interval?
What is 12?
500
You are comparing male and female gerbils whose water was laced with either Valium, Tylenol, or a placebo. You would use this test.
What is a two-way ANOVA?
500
A correlation on ranks instead of scores.
What is a Spearman?
500
mu1=mu2=mu3 is an example of this type of hypothesis.
What is a null hypothesis?
500
The men in my study scored significantly higher than the women ONLY if they were tested in the morning and not the evening. What kind of effect have I found?
What is an interaction?
500
The graph of this distribution has one very, very high score. This is how it is described.
What is a positively skewed distribution?
