Devi rides the bus to her grandmother’s house every day. She tracked how many minutes the bus rides took for one week:

24 32 25 24 30 30 24

1 answer

To analyze Devi's bus ride times, we can calculate several statistical measures, including the mean, median, mode, and range.

Here are the ride times for one week:

  • 24
  • 32
  • 25
  • 24
  • 30
  • 30
  • 24

1. Mean

The mean is calculated by adding all the values together and dividing by the number of values.

\[ \text{Mean} = \frac{(24 + 32 + 25 + 24 + 30 + 30 + 24)}{7} \] \[ \text{Mean} = \frac{189}{7} \approx 27 \]

2. Median

To find the median, we first need to sort the numbers:

24, 24, 24, 25, 30, 30, 32

Since there are 7 values (an odd number), the median will be the middle value:

\[ \text{Median} = 25 \]

3. Mode

The mode is the number that appears most frequently in the data set. In this case:

  • 24 appears 3 times
  • 30 appears 2 times
  • 25 appears 1 time
  • 32 appears 1 time

Thus, the mode is:

\[ \text{Mode} = 24 \]

4. Range

The range is the difference between the largest and smallest values in the data set.

\[ \text{Range} = 32 - 24 = 8 \]

Summary of Results:

  • Mean: 27
  • Median: 25
  • Mode: 24
  • Range: 8

These statistics provide insights into Devi's bus ride times for the week.
