Monthly rentals for 41 holiday homes in a resort
Samples from a distribution such as a normal distribution can be used to help assess whether skewness, clusters or outliers in a real data set could have appeared by chance.
Select random samples (from a normal distn with the same mean and sd as the actual strength data).
The random samples rarely appear as skew as the real data, giving strong evidence that the rentals have a skew distribution.
The data are artificial but are supposed to be the monthly rents asked for 41 houses in a holiday resort.
