Random functions

Enter the formula =RAND() and copy it down to obtain 100 random numbers

Calculate the mean, standard deviation, median, first and third quartiles

Use an IF to interpret any number less than 0 Use an IF to interpret any number less than 0.5 as “Tails” and any other number as “Heads”

Use the COUNTIF function to see how many heads and tails you get

Use the formula =RANDBETWEEN(1,6) to generate 100 integers between 1 and 6

Calculate the Frequencies of the values 1 through 6 Calculate the Frequencies of the values 1 through 6. (Remember “array formula”)

Create a histogram for the frequencies.
