How to calculate Mean, Mode, Median and Range
There are different methods which you can use to find the average of a set of data; mean, mode and the median. The next few videos will explain to you what the mean, mode and median are and how to calculate them. You will learn that the mean is the sum of all the values divided by the amount of values, the mode is that piece of information with the highest frequency and the median is the mid-value after ordering the data. You will also learn when it is more appropriate to use the mean for instance and when the mode or the median would be a better method to say something about the average. Have a look at the following maths example questions to understand exactly what the mean, mode and median are. You will also understand what the range of a set of data is. Good luck and have fun!!
Solving example questions about Mean, Mode, Median and Range
You now understand the difference between mode, median and mean. Please study all of the following 4 videos explaining mean, median and mode during your maths revision. Each video will contain something new you need to know and understand for your IGCSE GCSE maths exam. Each video will ask you a new question or will show you what many students do wrong. So prepare yourself well, check all the resources below and pass your next maths exam! Let me know on the forum of this site if you still don't understand mean, mode and median. If you tell me I will help you with your maths and make some more maths example questions for you. Good luck and have fun!
Past Paper Exam Question involving Mode, Median and Mean
One of you asked me to help solving the following exam question involving mode, median and mean. I will also explain to you how to calculate the mean when given a grouped frequency table. Finally you will learn what a histogram is and what is meant with frequency density.
Once you have studied all the resources above explaining mean, mode and median, I am sure you will appreciate this poster. The display hangs in my classroom. Students never really understand the joke until the day I explain mean, mode and median to then. All of a sudden I will hear some students laughing. The world made a little bit more sense to them.
