Question

find the three measures of central tendency (the mean, median, and mode). (if an answer does not exist, enter dne.)
9, 16, 25, 36, 49
mean
median
mode

Explanation:

Step1: Calculate the Mean

The mean is the sum of the numbers divided by the count of numbers. The numbers are 9, 16, 25, 36, 49. The sum is \(9 + 16 + 25 + 36 + 49 = 135\). There are 5 numbers, so the mean is \(\frac{135}{5}=27\).

Step2: Find the Median

The median is the middle number when the numbers are arranged in order. The numbers are already in ascending order: 9, 16, 25, 36, 49. The middle number (3rd term) is 25.

Step3: Determine the Mode

The mode is the number that appears most frequently. Each number appears only once, so there is no mode (enter DNE).

Answer:

mean: 27
median: 25
mode: DNE
