What is Range, Median, and Average of a Data Distribution:
- Range = max - min
- Median = middle value
- Average = total sum of values/number of values.
Range for hours spent studying for 10 - 13 year olds = 8 - 1 = 7
Range for hours spent studying for 14 - 17 year olds = 10 - 4 = 6
Median for hours spent studying for 10 - 13 year olds = 4
Median for hours spent studying for 14 - 17 year olds = 7
Average for hours spent studying for 10 - 13 year olds = (1+1+2+4+4+4+4+6+6+7+8)/11 = 4.3
Average for hours spent studying for 14 - 17 year olds = (4+4+4+4+6+7+8+9+9+10+10)/11 = 6.8
Therefore, we can conclude that: the 14- to 17-year olds spent more hours (6.8 hours) studying, on average, last weekend than the 10- to 13-year olds (4.3 hours).
