ORIGINAL SILENT CAPTIONED LESSON
0–4 seconds: One list, two summaries. Find the mean and median of 2, 3, 4, 5, 26.
4–8 seconds: Mean uses every value. The sum is 40; divide by five to get 8.
8–12 seconds: Median is the middle value. The sorted list has five values; the third is 4.
12–16 seconds: The large value changes the mean. Mean 8, median 4. The value 26 pulls the mean above the middle value.
16–20 seconds: Your turn. Replace 26 with 6. What are the mean and median of 2, 3, 4, 5, 6?
ANSWER KEY: The new sum is 20. The mean is 20 divided by 5, which is 4. The median is the third sorted value, also 4.
