Answer:
Mean and median of categorical data cannot be found. Mode would be the most often observed value.
Step-by-step explanation:
The mean and median of the data cannot be found.
The mode of the data can be found and it is junior.
The mean of data is the average value of the whole data.
It is calculated by adding all the terms and dividing the total by the number of terms.
Mean = ∑x/n, where x represents variables, and n represents the number of variables.
The median of data is the middlemost value in the data when the data is arranged in ascending or descending order.
When we have an odd number of observations say n,
Then median = (n + 1)/2th observation.
When we have an even number of observations say n,
Then median = { n/2th observation + (n/2 + 1)th observation}/2
The mode of data is the variable with the maximum frequency.
We are provided with the class levels of 28 students as follows:
Freshman: 5
Sophomore: 2
Junior: 11
Senior 10
To calculate the mean and median we need numeric data, but we are provided with categorical data only. So we can't calculate the mean and the median of this data.
The mode can be calculated as it is just the data with maximum frequency. In the provided data, the mode is Junior.
