Past Paper Question about Histograms and calculating an Estimate of the Mean
How to create a Histogram with Frequency Density, calculate Probability, find the Modal class and Quartiles: a Past Paper Question
Study the following Maths Past Paper Exam Question about Histograms. I will explain to you how to create a Histogram with Frequency Density. You will understand that the area of one of the bars of a histogram with frequency density equals to the actual frequency of that group. This Past Paper Question will also show you how to calculate Probability and how to find Quartiles and the modal class. Good luck and let me know if you need more help with your maths!
