Scales of Measurement
This scale of measurement identifies or names a category, person, etc.
What is Nominal?
This type of statistics summarizes and organizes numbers so they are easier to understand/digest.
What is Descriptive Statistics?
This is a display of scores that are ranked in numerical order.
What is Frequency Distribution?
These are the three measures of central tendency that you will be asked to calculate in this class.
What are Mean, Median, and Mode?
This is the shape of a normal distribution.
What is a Bell/Bell Curve?
This scale of measurement features an equal distance between possible points on a scale, but there is no true 0.
What is Interval?
Descriptive statistics answer these types of questions.
What is "What is?" or "How many?"
This way of displaying frequency distribution lets you easily see the highest and lowest numbers, as well as where scores "cluster" together.
What is Numeric Presentation?
This is the average of scores in a distribution.
Rare events or observations occur at this part of a normal distribution.
What are the Tails?
This scale of measurement allows you to compare numbers proportionally because there is a true 0.
What is Ratio?
This type of descriptive analysis looks at two categories.
What is Bivariate?
This type of graph displays a frequency distribution.
What is a Histogram?
This is the most central number or score in a frequency distribution.
What is the Median?
This type of graph can look similar to a normal distribution.
What is a Histogram?
This scale of measurement ranks variables in order from highest to lowest.
What is Ordinal?
Univariate descriptive analysis deals with these mathematical concepts.
What are Mean, Median, or Frequency Distribution?
This is the "frequency" counted in a frequency distribution.
What is the Number of Times a Score Occurs?
This score occurs most frequently in a distribution.
What is the Mode?
These three measurements are very similar or equal in a normal distribution.
What are Mean, Median, and Mode?
In statistics, these two levels of measurement are treated the same.
What are Interval and Ratio?
This type of descriptive analysis is used when working with simple correlation.
What is Bivariate?
This is the number of trees that measure no more than 85 ft. tall.

What is 29?
These three numbers are the mean, median, and mode of the following frequency distribution:
5 5 9 10 12 12 14 16
What are 10.625 (mean), 11 (median), and 5 & 12 (mode)?
This distance from the mean represents 95% of all scores.
What is 2 SDs Above the Mean?
