These histograms represents snowfall data in inches from 04-05 and 05-06 dec 1st

Question

These histograms represents snowfall data in inches from 04-05 and 05-06 dec 1st through march 31st for both periods.

Please explain and compare graphs in terms of the shape of the graph for example is it unimodal? skewed? etc. What does the centers for these histograms represent and the spread. Define first what these terms mean (shape ,spread ,center)

Explanation / Answer

Center

Graphically, the center of a distribution is located at the median of the distribution. This is the point in a graphic display where about half of the observations are on either side. In the chart to the right, the height of each column indicates the frequency of observations. Here, the observations are centered over 4.

Spread

The spread of a distribution refers to the variability of the data. If the observations cover a widerange, the spread is larger. If the observations are clustered around a single value, the spread is smaller.

Shape

The shape of a distribution is described by the following characteristics.

These graphs are clearly unimodal as both have a clear one peak data.

Also, the spread for both is very less as there is a peak at one particular frequency. Firat graph spreads from 0 to 400 inches and second spreads from 0 to 15 inches.

Observations here are centred over 0 to 1 inches
