Uhh I'm confused this is probably really easy to most people but I need help what is the upper quartile and interquartilerange for these following questions

1.)56,45,37,43,10,34

2.)77,78,68,96,99,84,65

3.)30,90,40,70,50,100,80,60

4.)4,5.2,1,3,2.4,6,3.7,8,1.3,7.1,9

5.)25,56,13,44,0,31,73,66,4,29,37

6.)234,648,369,112,527,775,406,268,400

You need to put them in numerical order, then the upper quartile is the 75% piece of data, so it's the one that's 3/4 away from the bottom.. So if you have 12 pieces of data it's the 12*3/4 = 9th piece of data, if it doesn't fall on a piece of data, you'll have to work out where it is in between the 2 adjacent pieces of data.

The interquartile range is the difference between the 75%th and the 25%th pieces of data.

Let me know if you don't understand any of this :)
