answers solved correctly
Information collected in a numerical form is called
quantitative
Which measure of central tendency is at the highest point on a graph?
mode
Correlation coefficient tests allow you to determine if a cause and effect
relationship is present.
false
Data that are categorical but can be rank-ordered in a meaningful way are called:
ordinal
If the mean is to the left of the median, what is true?
The distribution is negatively skewed.

standard deviation
A variable with equal distances between score units which also has a true
meaningful zero is:
ratio
When calculating a Pearson's correlation coefficient, it is necessary that both
variables have approximately normal distributions.
