Pie Chart

A

Pie charts show the distribution of a categorical variable as a “pie” whose slices are sized by the counts or percents for the categories. A pie chart must include all the categories that make up a whole.

Q

SOCS

A

Describing the Overall Pattern of a Distribution – Remember your SOCS
To describe the overall pattern of a distribution, address all of the following:

Spread – give the lowest and highest value in the data set

Outliers – are there any values that stand out as unusual?

Center – what is the approximate average value of the data (only an estimation)

Shape – does the graph show symmetry, or is it skewed in one direction (see below)

33
Q

Outlier

A

An outlier in any graph of data is an individual observation that falls outside the overall pattern of the graph.
