5.4 NORMAL DISTRBUTION CURVE





To day we did 5.4 the normal distribution we looked at 4 different kinds of histograms



















The first one is called a single point histogram or NORMAL DISTRBUTION CURVE the pink one is skewed
The blue one is a bi- modal and the orange one is uniform
Than we did a thing that involved rolling a dice 50 times and recording the sum of the numbers
Than we combined the whole class’ results and made the histogram
It was like the purple one with the top ones being 7 and 8
Than we looked at this graph



















And this gave the standard deviation purpose. Telling us a lot about one set of data
Next is joel
