For the given data of the precipitation depth for some years at some stations in Saudi Arabia
Station # A121, it is required to:
1) Plot the time series of precipitation depth.
2) Draw the histogram of absolute frequency, relative frequency, and cumulative
absolute and relative frequencies for different class intervals. [Use # of classes=7].
3) calculate the different means (arithmetic, geometric, harmonic, median, mode,
etc.) of the data use grouping and ungrouping of the data, plot the different means
on the time series plot of Q1.1. Notice the differences and explain.
4) calculate the variance and standard deviation of both data and check your results
with spreadsheet for grouped and ungrouped data. Notice the differences and
explain. Plot the arithmetic mean \pm standard deviation on the time series plot of 1.
5) calculate the skewness, and the kurtosis coefficients of the for grouped and
ungrouped data and.
