Math Problem Statement
Solution
Let's analyze and answer the questions based on the data provided in the image:
The list of amounts donated by 9 taxpayers is:
(a) Median:
To find the median, we need to first order the dataLet's analyze and answer the questions based on the data provided in the image:
The list of amounts donated by 9 taxpayers is:
(a) Median:
To find the median, we need to first order the
Since there are 9 numbers, the median is the middle value, which is the 5th number:
(b) Mean:
The mean is calculated by summing all the values and dividing by the number of data points.
(c) Modes:
A mode is the number that appears most frequently in the dataset. Checking the list:
Each number appears exactly once, so there is no mode. The answer is zero modes.
Summary of Answers:
- (a) Median: 44
- (b) Mean: 48.6
- (c) Mode: Zero modes
Do you want more details or have any questions?
Here are five relative questions to deepen understanding:
- How would the mean change if one more large donation was added?
- Can a dataset have more than two modes, and what would that look like?
- What happens to the median if the dataset has an even number of values?
- How would the range of this dataset be calculated?
- Is it possible for the mean to be less than the median in a different dataset?
Tip: The mean is sensitive to extreme values (outliers), while the median gives a better sense of the center for skewed distributions.
