Question

a survey was conducted among a group of employees to find the average time they spent online each day. the answers of the employees (in minutes) are shown in the box. 25, 45, 60, 30, 35, 20, 40, 45, 15, 30. which of these scales would be most appropriate on the y - axis to represent this data on a bar graph? 1 minute 3 minutes 5 minutes 10 minutes

Explanation:

Step1: Identify data range

The data values are 25, 45, 60, 30, 35, 20, 40, 45, 15, 30. The minimum value is 15 and the maximum value is 60.

Step2: Analyze scale options

• If the scale is 1 minute, the graph will be too detailed and may look cluttered.
• If the scale is 3 minutes, it is not a very common or convenient scale for graph - making.
• If the scale is 5 minutes, it can evenly represent the data values in a clear and not - too - cluttered way. For example, 15, 20, 25, 30, 35, 40, 45, 60 are all multiples of 5.
• If the scale is 10 minutes, some of the data points may not be represented as precisely.

Answer:

5 minutes
