Exercise
Design a data set showing a normal probability density function

Try to design an artificial data set containing 1000 "measurements" on a single variable, which show a standard normal probability density function. Calculate the most important measures of location and variation. Expand this data set by one column and create another data set in the new column which is normally distributed around a mean of 122 with a standard deviation of 18.

Use the to obtain the following material:
 


Hint: Use the formula editor of DataLab for creating the random numbers. As an alternative you can use the random number generator contained in the tools section of the Teach/Me distribution.
