Example of finding the range. Examine the peaks and spread of the distribution. Facet_grid(year ~.) this part.count./nrow(d) won't work and needs the sample size for each year when i facet. The peaks represent the most.

Descriptive Statistics

Decide on the width of each bin. Our best estimate of the mean would be: There is no strict rule on how many bins to use—we just avoid using too few or too many bins..

Decide on the width of each bin. The frequency of the ith bin. In order to draw a histogram: Normalize the histograms so that all of the bar heights add to 1, and use a uniform bin width. The table shows the ages of 25 children on a school trip.

Obviously, a tiny sample size such as 3 or 5 is not suitable for histogram. Class width = range / number of intervals next, develop a table or spreadsheet with frequencies for each interval. Use the frequency density and class intervals to create suitable vertical and horizontal axes.

If we go from 0 to 250 using bins with a width of 50 , we can fit all of the data in 5 bins. Multiply by the bin width, 0.5, and we can estimate about 16% of the data in that bin. For example, consider the following histogram:
