Preparing Data for Analysis Review - correct answer ✔
A demand characteristic is - correct answer ✔When a person responds in an experiment in a way that
is consistent with their beliefs about how the experimenter would like them to behave.
If a test is valid, what does this mean - correct answer ✔The test measures what it claims to measure.
A predictor variable is another name for - correct answer ✔An independent variable
A frequency distribution in which high scores are most frequent (i.e. bars on the graph are highest on
the right hand side) is said to be - correct answer ✔Negatively skewed
A large standard deviation (relative to the value of the mean itself) - correct answer ✔indicates that the
data points are distant from the mean (i.e. the mean is a poor fit of the data).

In SPSS, where in the "Analyze" menu can you find t-tests - correct answer ✔"Compare Means"
In SPSS, where in the "Analyze" menu can you find one-way ANOVA - correct answer ✔"Compare

Central Tendency & Dispersion - correct answer ✔
Imagine we took a group of smokers, recorded how many cigarettes they smoked each day and then
split them randomly into one of two 6-week interventions; 'hypnosis' or 'nicotine patch'. After the 6
weeks, we again recorded how many cigarettes they smoked each day and subtracted this number from
the number of cigarettes they each smoked pre-intervention, to produce a intervention success score
for each participant. Out of the following options, which would be the best method of displaying the
results? - correct answer ✔A simple boxplot with the variable 'intervention method' on the x-axis and
'intervention success' on the y-axis.
The Kolmogorov-Smirnov test can be used to test - correct answer ✔Whether scores are normally
distributed.
The assumption of homogeneity of variance is met when - correct answer ✔The variances in different
groups are approximately equal.
A _____ is a numerical characteristic of a sample and a _____ is a numerical characteristic of a
population - correct answer ✔statistic, parameter
A kurtosis value of -2.89 indicates - correct answer ✔A flat and light-tailed distribution.
Levene's test can be used to measure - correct answer ✔Whether group variances differ.
Normality & Outliers - correct answer ✔
