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.
