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!

Task

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.

Conclusion

 

                                                             20130520054706aLahu.jpg

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!!

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.
