Introduction
Good morning learners. Today we are going to focus on measures of central tendency an spread (mean, median, mode and range). Please watch the video I have made for you below to find out more about this topic.
Task
In this task you are going to summarize data through calculations, using the different measures of central tendency. Below are links to videos with examples on how to do the required calculation:
Mean:
Mode:
Median:
Range:
Process
Question 1
Find the mean of this data set
2 3 3 5 5 6 8 9 9 10
Question 2
What is the mode of this data set?
0, 1, 1, 2, 2, 3, 4, 5, 6, 6, 6, 7, 7, 8
Question 3
3.1 What is the median of this data set?
32, 43, 45, 55, 87
3.2 Find the median of this data set
46, 65, 33, 32, 47, 70
Question 4
Find the range for the following data set
21, 65, 12, 43, 85, 24, 31, 64, 77
Evaluation
For every answer I require a step by step indication of how it was calculated, just like it is shown on the examples.
Conclusion
As a summary and an indication that you have understood today's lesson, please write a brief explanation in your own word about the difference between the mean and the median and as well as the difference between the range and mode.
