Answer:
Median- 12
Q1- 5
Q3- 43
IQR- 38
Step-by-step explanation:
2, 5, 11, 13, 43, 45
Put your numbers in order of least to greatest
Since there is no given median as the amount of numbers is even, find the number in between the 2 middle numbers, in this case, the number would be 12, as it is in between 11 and 13.
To find Q1 and Q3, you need to find the first and third median, which would be 5 and 43. To find the IQR, you need to subtract Q3 from Q1, which would give you 38 in this equation
