2. Create and post an example that has a data set of 15 to 25 numbers, similar to the example in the Introduction above. Do not find the mean, median, mode, range and standard deviation of your data set.
Mean - Mean is the average of all data points available.
It is defined as sum of all the data points divided by number of data points.
Median - It is value of data point which falls in the middle when we arrange all samples in ascending order.
Mode - It is value of data point which is repeated maximum times.
Range - It is the difference between minimum and maximum value of the data points present in our sample.
Standard deviation - It represents how much the data points in the sample differ from the mean value of the sample.
