Question

The following are the ages (in years) of some children who reported at a health centre

a week ago. 7 11 14 10 8 11 9
Use it to find each of the following:
(a) Range (b) Median (e) Mode

Answer 1

The range of the children's ages is 7 years, the median age is 10 years, and the mode is 11 years.

Step-by-step explanation:

To find the range, median, and mode of the given ages of children, we proceed as follows:

• First, we order the data: 7, 8, 9, 10, 11, 11, 14. This step makes it easier to find the median and the mode.
• The range is the difference between the highest and lowest values. In this case, range = 14 - 7 = 7 years.
• The median is the middle number in an ordered data set. Since there are 7 numbers, the median is the 4th number: 10 years.
• To find the mode, we look for the number that appears most often. Here, the number 11 appears twice, more than any other number, so the mode is 11 years.
