Answer:
I can help you with that. Let's break down the question step by step:
Part A:
1. Calculate the mean:
To find the mean, you add up all the values and then divide by the total number of values. In this case, you would add up all the minutes spent practicing over the 10 days and then divide by 10.
2. Calculate the median:
To find the median, you first need to order the values from smallest to largest. Then, if there is an odd number of values, the median is the middle number. If there is an even number of values, the median is the average of the two middle numbers.
Part B:
1. Measure of center to show the teacher:
Since the student wants to show the teacher that they have practiced long enough for the day, they should use the median as the measure of center to present to their teacher.
- Explanation: The median represents the middle value when the data is ordered, which can give a better indication of the typical amount of time spent practicing. This measure is less affected by extreme values compared to the mean, making it a more appropriate choice to demonstrate consistency in practice time.
