Question 1
The histogram shows the ages (in months) that babies learned to walk. Use this histogram to solve the problem.
(i) Find the median age that a baby learned to walk.
(ii) Find the third quartile by determining the median of the upper half of the data.
◦ (i) median = 12.5;
(ii) first quartile = 13
◦ (i) median = 11;
(ii) first quartile = 12
◦ (i) median = 12;
(ii) third quartile = 13
◦ (i) median = 11.5;
(ii) first quartile = 12.5
Question 2
The histogram shows suicide rates per 100,000 residents of Country X and the number of states that had these rates. Use this histogram to solve the problem.
(i) Find the median suicide rate per 100,000 residents for Country X by state.
(ii) Find the first quartile by determining the median of the lower half of the data.
◦ (i) median = 18.5;
(ii) first quartile = 16
◦ (i) median = 18;
(ii) first quartile = 14.5
◦ (i) median = 19.5;
(ii) first quartile = 17
◦ (i) median = 19;
(ii) first quartile = 15.5
