1.Create a tally chart

2.Find the range

Answer: 5.96-5.50 = 0.46

3.Determine the cell interval (this number must be an odd integer as discussed in the lecture)

I= R/1+3.322logn= 0.46/1+3.322log(37)

=0.46/4.322*1.56820

=0.46/677776

=0.06786

=0.07

4.Determine the cell midpoints (these are the center values for each cell)

5.Determine the cell boundaries (these are the lower and upper boundaries as discussed in the lecture)

6.Post the cell frequency

7.Construct a Histogram (Bonus +5pts)
