Find the mean and median of the past week's temperatures

Question

Sunday=102 degrees Fahrenheit
monday= 105
tuesday=107
wednesday=109
thursday=110
friday=109
saturday=109

Answer 1

To find the mean and median of the past week's temperatures, we first list the temperatures for each day:

• Sunday: 102 degrees
• Monday: 105 degrees
• Tuesday: 107 degrees
• Wednesday: 109 degrees
• Thursday: 110 degrees
• Friday: 109 degrees
• Saturday: 109 degrees

Mean Calculation:

1. Add all the temperatures together: \[ 102 + 105 + 107 + 109 + 110 + 109 + 109 = 751 \]

2. Count the number of days (which is 7).

3. Divide the total by the number of days to find the mean: \[ \text{Mean} = \frac{751}{7} \approx 107.29 \text{ degrees} \]

Median Calculation:

1. First, we arrange the temperatures in ascending order: \[ 102, 105, 107, 109, 109, 109, 110 \]

2. Since there are 7 numbers (an odd count), the median will be the middle number, which is the 4th number in the ordered list: \[ \text{Median} = 109 \text{ degrees} \]

Summary:

• Mean temperature: approximately 107.29 degrees Fahrenheit
• Median temperature: 109 degrees Fahrenheit
