100
This type of graph is segmented into "slices" and represents nominal data
A pie chart
100
This measure of central tendency is the only one that can be used for nominal data
What is mode?
100
Gender, hair color, and political party affiliation fall under this level of measurement.
What is nominal?
100
This index represents the maximum - minimum
What is range?
100
Another term for "output variable" is this
What is dependent variable?
200
This type of graph looks similar to a bar graph but represents interval-ratio data
What is a histogram?
200
You would divide by this number to get the mean of the following scores:
2, 4, 7, 9, 12, 11
What is 6?
200
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?
200
This index represents the middle 50% of scores
What is the interquartile range or IQR?
200
This ranges from 0 to 1 to represent the amount out a "whole"
What is a proportion?
300
The shape of the histogram seen here
What is a negative skew?
300
This measure is more resistant to outliers, often used when data is skewed.
What is the Median?
300
Name the two levels of measurement that can be used to measure the variable "income"
What are ordinal and interval-ratio?
300
The square of standard deviation is this
What is variance?
300
This is a small subset of the population from which researchers gather data
What is a sample?
400
The sum of the individual interval/category frequencies up to a point
What is cumulative frequency?
400
Distributions that have very few low values are described as this
What is negatively skewed?
400
Nominal and Ordinal variables are considered to fall under this type of data
What are categorical data?
400
This graphic device can show the "five number summary" which can visualize the spread of scores
What is a box plot?
400
Consider the following distribution of scores: 20, 50, 80, 91, 100. Which score corresponds to the 50th percentile in this distribution?
What is 80?
500
Spaces between bars in a histogram typically represent this
What is a gap in the data?
500
This term is used to describe a distribution that has two most frequently occurring scores
What is bimodal?
500
This falls under interval-ratio variable and can be measured with infinitely many fractions of a whole number
What is a continuous variable?
500
If variance is 4900, the standard deviation would be
What is 70?
500
This is the type of statistical procedures that can draw conclusions across more than one variable at a time
What are inferential statistics?
