Using the data of all the ages of everyone in the class, find the following: mean, median, mode(s), standard deviation enter integer or decimal number
Solution
Let's calculate the statistical measures for the provided data set:
Data Set:
17, 17, 18, 18, 19, 19, 20, 20, 20, 21, 21, 21, 21, 22, 23, 24, 26, 28, 29, 29, 30, 32, 32, 32, 33, 35, 37, 38, 40, 52
1. Mean (Average)
The mean is the sum of all the values divided by the number of values.
2. Median
The median is the middle value when the numbers are arranged in order. If there is an even number of values, the median is the average of the two middle values.
3. Mode(s)
The mode is the value(s) that appears most frequently.
4. Standard Deviation
The standard deviation is a measure of the amount of variation or dispersion of the data set.
I'll calculate these values for you.Here are the calculated values based on the provided dataHere are the calculated values based on the provided
- Mean (Average): 26.47
- Median: 23.5
- Mode: 21 (appears most frequently)
- Standard Deviation: 8.23
Would you like more details or have any other questions?
Here are 5 related questions for further exploration:
- How would the statistics change if you added more data points?
- What is the effect of outliers, like 52, on the mean and standard deviation?
- How do you calculate the variance from the standard deviation?
- What happens to the median if we remove the largest value, 52?
- How can the standard deviation help us understand the spread of the data?
Tip: The mode is not always unique. A data set can have more than one mode if multiple values appear with the same highest frequency.
