a movie store tracked the number of movies that customers rented last month. renting movies last month what is the median of the numbers?
Answer
Explanation:
Step1: Count total data - points
There are 4 + 5+ 6 = 15 data - points.
Step2: Use median formula for odd - numbered data
For a set of (n) data - points (where (n = 15) is odd), the median is the (\left(\frac{n + 1}{2}\right))-th value when the data is arranged in ascending order. (\frac{15+ 1}{2}=8)-th value.
Step3: Find the 8 - th value
Counting from the left (1 movie rented) in ascending order: 4 values for 1 movie rented, then starting to count for 2 movies rented. After 4 values of 1 movie rented, the 5 - th to 9 - th values correspond to 2 movies rented. So the 8 - th value is 2.
