Math Problem Statement
Solution
The problem asks to find the median and mean of the given IQ scores:
1. Mean (Average):
The mean is calculated by summing up all the values and dividing by the total number of values.
2. Median:
To find the median, first arrange the scores in ascending order:
Since there are 5 numbers (an odd number), the median is the middle value, which is 80.
Final Answer:
- Mean: 89.4
- Median: 80

Here are 5 related questions for further practice:
- What is the mode of the given data set?
- If a new IQ score of 90 is added, what would be the new mean?
- What is the range of the given IQ scores?
- If the lowest score is removed, how does the median change?
- Can the mean be affected more by extreme values than the median? Why?
Tip: The median is a better measure of central tendency than the mean when dealing with outliers.
