Question

The distances travelled weckly (in miles) by 150 randomly selected students at Ghana Communication Technology is given as follows: Required (a) Find the arithmetic mean and the median.

Answer 1

To find the arithmetic mean, add up all the distances and divide by the number of students. To find the median, arrange the distances in order and find the middle value or average of two middle values.

Step-by-step explanation:

To find the arithmetic mean of the distances travelled weekly by the 150 randomly selected students, you need to add up all the distances and divide by the number of students. The arithmetic mean is also called the average.

To find the median, you need to first arrange the distances in order from least to greatest. Then, find the middle value. If there is an even number of values, take the average of the two middle values.

For example, let's say the distances travelled weekly by the 150 students are as follows: [10, 15, 12, 8, 11, 9, 13, ...]

Arithmetic mean = (10 + 15 + 12 + 8 + 11 + 9 + 13 + ...) / 150

Median = middle value or average of two middle values
