This type of graph is segmented into "slices" and represents nominal data
A pie chart
This measure of central tendency is the only one that can be used for nominal data
What is mode?
Gender, hair color, and political party affiliation fall under this level of measurement.
What is nominal?
This index represents the maximum - minimum
What is range?
Another term for "output variable" is this
What is dependent variable?
This type of graph looks similar to a bar graph but represents interval-ratio data
What is a histogram?
You would divide by this number to get the mean of the following scores:
2, 4, 7, 9, 12, 11
What is 6?
A survey question asks respondents to rate their satisfaction on a scale from 1 to 5. This is an example of this level of measurement.
What is Ordinal?
This index represents the middle 50% of scores
What is the interquartile range or IQR?
This ranges from 0 to 1 to represent the amount out a "whole"
What is a proportion?
The shape of the histogram seen here

What is a negative skew?
This measure is more resistant to outliers, often used when data is skewed.
What is the Median?
Name the two levels of measurement that can be used to measure the variable "income"
What are ordinal and interval-ratio?
The square of standard deviation is this
What is variance?
This is a small subset of the population from which researchers gather data
What is a sample?
The sum of the individual interval/category frequencies up to a point
What is cumulative frequency?
Distributions that have very few low values are described as this
What is negatively skewed?
Nominal and Ordinal variables are considered to fall under this type of data
What are categorical data?
This graphic device can show the "five number summary" which can visualize the spread of scores
What is a box plot?
Consider the following distribution of scores: 20, 50, 80, 91, 100. Which score corresponds to the 50th percentile in this distribution?
What is 80?
Spaces between bars in a histogram typically represent this
What is a gap in the data?
This term is used to describe a distribution that has two most frequently occurring scores
What is bimodal?
This falls under interval-ratio variable and can be measured with infinitely many fractions of a whole number
What is a continuous variable?
If variance is 4900, the standard deviation would be
What is 70?
This is the type of statistical procedures that can draw conclusions across more than one variable at a time
What are inferential statistics?
