Bot GPT 4-o mini To find the median and mean of the reported number of movies, we will first list the data provided:
The number of movies seen by each student is:
13, 12, 9, 4, 9.
Step 1: Calculate the Median
To find the median, we need to arrange the numbers in ascending order:
4, 9, 9, 12, 13.
Since there are 5 numbers (an odd count), the median is the middle number.
In this ordered list, the middle number (3rd position) is 9.
So, the median is 9.
Step 2: Calculate the Mean
To calculate the mean, we need to sum all the numbers and then divide by the number of values.
Sum of the numbers:
4 + 9 + 9 + 12 + 13 = 47.
Now, divide by the number of students (5):
Mean = Total Sum / Number of Values = 47 / 5 = 9.4.
So, the mean is 9.4.
Summary of Results
- Median: 9
- Mean: 9.4
