some friends discussed the sizes of their coin collections. coin collections what is the median of the numbers?
Answer
Explanation:
Step1: List the number of coins
From the bar - chart, the number of coins for each person is: Emily has 10 coins, Tyrone has 70 coins, Angie has 5 coins, Chloe has 35 coins, Lucy has 85 coins, Jeanette has 45 coins, Kelly has 55 coins.
Step2: Arrange the numbers in ascending order
5, 10, 35, 45, 55, 70, 85.
Step3: Find the median
Since there are 7 numbers (an odd - numbered data set), the median is the middle number. The middle number of 7 numbers is the 4th number when arranged in ascending order. So the median is 45.
Answer:
45
