Find the mean and the median of the past week’s temperatures.
During the week, the mean temperature was __ degrees.
During the week, the median temperature was __ degrees.

1 answer

To calculate the mean and median of the temperatures for the week, we first list the temperatures:

  • Sunday: 45 degrees
  • Monday: 52 degrees
  • Tuesday: 44 degrees
  • Wednesday: 62 degrees
  • Thursday: 55 degrees
  • Friday: 49 degrees
  • Saturday: 50 degrees

Step 1: Calculate the Mean

The mean is found by adding all the temperatures together and dividing by the number of temperatures.

  1. Sum of temperatures: \[ 45 + 52 + 44 + 62 + 55 + 49 + 50 = 357 \text{ degrees} \]

  2. Number of days: There are 7 days in the week.

  3. Mean temperature: \[ \text{Mean} = \frac{357}{7} = 51 \text{ degrees} \]

Step 2: Calculate the Median

The median is found by ordering the temperatures and finding the middle value.

  1. Order the temperatures:

    • 44 degrees
    • 45 degrees
    • 49 degrees
    • 50 degrees
    • 52 degrees
    • 55 degrees
    • 62 degrees
  2. Find the middle value: Since there are 7 temperatures, the median will be the 4th value in the ordered list.

    • The ordered temperatures are: 44, 45, 49, 50, 52, 55, 62.
    • The 4th value is 50.

Final Results

  • During the week, the mean temperature was 51 degrees.
  • During the week, the median temperature was 50 degrees.
