Quick reminder is this a central tendency - spread - symmetry question
1. These three question types have to do with the way the data in a
distribution is laid out.
Central Tendency
Spread
Distribution Shape
Central Tendency, Spread, or Distribution Shape?
Represents the point or area in the distribution of data where
scores tend to predominate or cluster.
Look for words like, average, mean, median, most common,
center point etc.
Distributions of data will tend to have a dispersion or spread
of scores around the central tendency.
Look for words like spread, range, variation, etc.
The shape of a distribution can be normal
Skewed or have other non-normalities
You will generally not see words in your problems that
request the shape of the distribution but it will be important
to know the shape to determine the type of central
tendency or spread statistics to use.
