Document Summary
This is in terms of fixing the data, where there is an unknown value, denoted as -9. * to fix this, you have to go through the data in excel, and change up the numbers so that it is just 0. This presents data, with comparing the results to each other. (in the australian road. They are used to quantitative data, which highlights the percentage of data in one class interval compared to another. It consists of a set of blocks which represent the percentages by area. When using histograms for continuous data, we need to use an endpoint convention, for the data points that border two class intervals. (having one side closed, the other open for example). How to produce a histogram by hand ( what is the height of each block per year) Common mistakes for histograms: make the block heights equal to the percentages, to many class intervals. The data is spread, but it s not symmetric.
