Since there is an uneven amount of numbers given, once you order them from least to greats take the two numbers in the middle (50,68) add them, and then divide by two. Your median will be 59. If there is an even amount of numbers, the number directly in the middle will be the median.
Dont know how to explain this one…(check picture if it helps)
Lower - 44
Upper - 68
The interquartile range is the upper quartile subtracted by the lower quartile.
IQR- 24
Sorry for any mistakes…its 6 in the mornings and I haven’t slept in two days! Good luck with the math!
