Question

1) . When making a frequency distribution table there should be a total of about how many intervals?
a. 1 to 3

b. 2 to 10
c. it depends on sample size

d. 5 to 6
e. 10 to 100

f. the number is given by Sturges' rule

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
