Tables of random numbers have the desired properties no matter how chosen from the table: by row‚ column‚ diagonal or irregularly. The first such table was published by a student of Karl Pearson’s in 1927‚ and

Mean: The average (mean) number of daily visitor traffic is 3 (total amount of data adds up to 88‚ then divided this total by the number of data sets‚ 30. 88 divided by 30‚ equals 2.93‚ which I rounded up to 3.) The average (mean) number of daily sales is 1 (total amount of sales data adds up to 29‚ then divided this total by the number of data sets‚ 30. 29 divided by 30‚ equals 0.96‚ which I rounded up to 1.)
