πππ Hey guys, let’s talk about charts that are best for exploring dispersion in a distribution! πππ
Histograms and box plots are two of the best charts for exploring dispersion in a distribution. Histograms show the frequency of values in a distribution, while box plots show the range and distribution of the values.
Histograms are great for showing the spread of values in a distribution. The x-axis shows the range of values, and the y-axis shows the frequency of those values. The shape of the histogram can tell us a lot about the distribution – if it’s bell-shaped, that means the values are tightly clustered around the center. But if it’s skewed to one side or has multiple peaks, that means the values are more spread out. The tails of the histogram show us the extreme values – the ones that are far away from the center.
The box in a box plot shows the range and distribution of the values in a distribution. The bottom and top of the box represent the first and third quartiles of the distribution, while the line inside the box represents the median (middle value). The whiskers show the range of the data, and any values that fall outside the whiskers are considered outliers. The length of the box and the length of the whiskers can tell us a lot about the spread of the values – if the box is short and the whiskers are long, that means the values are spread out over a wider range.
By using histograms and box plots, we can better understand the dispersion and variability in a distribution.
