# Measures of Central Tendency

Introduction

Samantha was given the following exam scores  80, 90, 87,59,100,87,72,95,87,72,76,92,85,95, 75,69,98,73,82,94,100 of 21 students in a chemistry class. From the following scores Samantha is require to find the mean, mode and median but she is having difficulties appreciating the concept of measures of central tendency. She attend classes regularly but she is still having challenges understanding the concept of measures of central tendency. Now Samantha is seeking your help to understand the concept of mean, mode and median.

Let's Take Samantha On A Journey!

At the end of the lesson students should be able to:

Understand the purposes of measures of central tendency

Determine at least 3 ways in which people used sets of data to find the mode, mean and median .

Define mean, mode and median in their own words.

Calculate mean, mode and median for sets of data.

Process

please use this link to watch and listen to a song on mean, mode and median.

Please use this link to watch a video game to understand the meaning of mode, mean and median.

Please use this link to watch a video on how to calculate the mean, mode and median.

Evaluation

 Criteria Very Good Good Poor Total Definition for mean, mode and median Students defined all 3 words, the words are fully explain, clearly understandable and is written in their own words. (6 Marks) Students defined two of the word and they are fully explain and are written in their own words. (4 Marks) Students defined one word in their own words. (2 Marks) Calculating the mean mode and median from given scenarios Students calculated the mode, median and mean from all scenarios given correctly.(5-6 Marks) Students Calculated the mode, mean and median from some scenarios given correctly .(3-4 Marks) Student calculated the mean, mode and median from one scenarios. (1-2 Marks) Determine at least 3 ways people used sets of data to find mode, median and mean Students determined at least three  ways people used sets of data to find mode, median and mean. (3 Marks) Students determined two ways people used sets of data to find mode, median and mean. (2 Marks) Students determined one way people used sets of data to find mean, median and mode. (1 Mark)

Conclusion

It can be concluded that different cites were used  to deliver the content of measures of central tendency. Hopefully the students had grasp the content fully and understand every concept of mean, mode and median and how it is used in the real world. There are other videos on YouTube that can be used to help you. Students may learn differently, therefore I encourage students and teachers to do things differently in order to improve the lesson so that students can have a better understanding of content been taught, for example if there are students in a class who are Physical or kinesthetic learners teachers should encourage student to manipulate objects and hands on activities that suit there learning style so that every students needs are cater for.

I hope you enjoy and understand the concept of Measures of Central Tendency during this web Quest.  I thank you for your hard work!!.

Credits

Firstly, I would like to thank God for giving me the strength and knowledge, so I could be able to complete this web quest,  Secondly, A special thank you to my lecturer for giving me this assignment to complete and for working really hard with us to ensure that we understand every step in the web quest process. It was a fun and excited opportunity to explore and I have learnt a lot about using this tool. Thank You!!

Teacher Page

This web quest was specifically created to help Grade 7 students. The purpose of this Web Quest is to introduce the students to Measures of Central Tendency (Mean, Mode and Median) and to help students construct some basic Knowledge of the topic and how it is used in the world. Students will be expose to videos and are require to complete activities in order to fully grasp the content.
