When a research says their experiment is "between subjects" it means the same as
I'm running a "before and after" study
subjects are in groups, each group exposed to level of independent variable
I have nominal or ordinal data
I have interval or ratio data
2
"Rejecting a null hypothesis" is the same as
I failed to find a practically significant result
I comitted a Type II error
I found a significant result
I failed to find a statistically significant result
3
A one-sample t test and an independent-samples t test are similar, and I see the difference.
False
True
4
I understand at least 90% of the concepts tested ; if not, raise your hand so we can discuss
False
True
5
Of the following, which can find a relationship between nominal or ordinal data?
paired/related samples t test
independent-samples t test
Chi-Square
ANOVA
6
When looking at SPSS correlation output, I will know where to find p value.
False
True
7
In research, a sample with high variability is
something that has nothing to do with population.
unlikely to be good at representing the population.
sometimes good and sometimes bad at representing a population.
likely to be good at representing the population.
8
The hypothesis that an effect or relationship does not exist in the population is:
two-tailed hypothesis
scientific / alternative hypothesis
one-tailed hypothesis
null hypothesis
9
True or False: In SPSS, the "Correlate" procedure is found under the Analyze menu.
False
True
10
A probability level that serves as a cutoff for a "significant result" is called
p value
alpha
the statistic
sample mean difference
11
When a researcher says their experiment is "within subjects" it means that
they have multiple, non overlapping groups
they use interval or ratio data
they use nominal or ordinal data
all subjects are exposed to all level of the independent variable
12
In SPSS, if I see "Sig.," I now know it's the same as p value.
False
True
13
One-tailed describes
One variable is being measured
One variable is manipulated
a hypothesis that doesn't specify a direction
a hypothesis that specifies a direction (e.g., greater than)
14
Of the tests in the choices, which one allows you to compare three means with one another?
independent-samples t test
ANOVA
Chi-Square
paired/related samples t test
15
If _______ is less than or equal to the alpha level, the "null hypothesis is rejected," indicating significance.
sampling error
the p value
the statistic
sample mean difference
16
I understand the difference between alpha level and p value.
False
True
17
In statistics, the most common measure of relationship, which analyzes at least one interval or ratio variable, is the
Pearson correlation
paired/related samples t test
standard deviation
Chi-Square
18
Ordinal data means
nonordered categorical responses (Yes / No)
equally spaced numerical responses in ratio
ordered categorical responses (e.g., 1st, 2nd, 3rd)
equally spaced numerical responses not in ratio
19
How many independent or subject variables are measured by a one-way ANOVA?
one
two
three
eight
20
In SPSS, a One-Samples T Test, an Independent-Samples T Test, a Paired Samples T Test, and Correlate all are found under
Data menu
Transform menu
Analyze
Graphs
21
Nominal data means
nonordered categorical responses (Yes / No)
equally spaced numerical responses in ratio
ordered categorical responses (e.g., 1st, 2nd, 3rd)
equally spaced numerical responses not in ratio
22
I understand what leads you to use a one-sample t test
True
False
23
"Descriptive values (e.g., means), value of test statistic, and p value associated with statistical value" - examples of
codebook
menu
output in SPSS
dataset
24
I understand the difference between one-tailed and two-tailed.
True
False
25
This statistical procedure, similar to a correlation, uses multiple variables to predict a dependent variable:
Kruskal-Wallis H test
independent-samples t test
Chi-Square
regression
26
Though SPSS reports "p-values," they don't call them p value. They use the term:
Integral
Differential
Sig.
Infinitesmal
27
A table like in the image above is associated with which statistical test:
one-sample t test
independent-samples t test
regression
Chi-Square test
28
t tests
: When you have a sample and wish to compare its mean to a population value, you want
a paired/related samples t test
a Mann-Whitney U test
an independent-samples t test
a one-sample t test
29
t tests
: When you have two samples' means and wish to see if they differ, you want a (an)
Mann Whitney U test
one-sample t test
independent-samples t test
paired/related samples t test
30
From the SPSS output shown in the image above, it can be concluded
the researcher ran a 1-tailed procedure
the researcher ran a 2-tailed procedure
the researcher knew there would be a correlation in a specific direction
the researcher ran a directional test
31
From the SPSS output shown in the image, it can be concluded
that there is no way to determine the p value from these output
the p value is .001
the p value is .882
the p value is 10
32
t tests
: If you want to compare two related samples or two sets of scores from a single person, you want
a one-sample t test
an independent-samples t test
a paired/related samples t test
a Mann Whitney U test
33
I understand the difference between "between subjects" and "within subjects"
True
False
