Study Notes
Data Analysis
- Data: 78, 81, 54, 2, 26, 13, 66, 23, 77, 15, 3
- Midrange: 41.5
- Mean: The average value of the data, not necessarily the most typical value.
- Median: The middle value when the data is ordered, better at representing typical values than the mean if outliers are present.
- Mode: The most frequently occurring value; these data have no mode.
- Interpretations: The midrange shows the data spread, the mean and median show average values. The results are meaningful since the sample size of 11 is large enough, and the data are numerical, not categorical.
