Referenced from lesson Spread of a Data Set
Find the measures of center and spread to summarize a column of your dataset.
The column I chose to summarize is .
Measures of Center
The three measures of center for this column are:
| Mean (Average) | Median | Mode(s) |
|---|---|---|
|
Since the mean is [higher/lower/about equal] compared to the median, this suggests the shape is [skewed right (or high outliers) / skewed left (or low outliers) / symmetric].
Measures of Spread
My five-number summary is:
| Minimum | Q1 | Q2 (Median) | Q3 | Maximum |
|---|---|---|---|---|
|
Displaying Center and Spread with a Box Plot
Draw a box plot from this summary on the number line below.
Be sure to label the number line with consistent intervals.
From this summary and box plot, I conclude:
