@TheSmartOne

OpenStudy (calculusxy):

For the first question, I got the mean as 92.1 , the median as 62, and I found that there was no mode.

OpenStudy (calculusxy):

I just want you to check if I am correct or incorrect.

OpenStudy (calculusxy):

And for the second one, I got the mean absolute deviation as: 51.9

jimthompson5910 (jim_thompson5910):

I don't see where they ask for the "mean absolute deviation"

OpenStudy (calculusxy):

Oh I didn't attach that part.

OpenStudy (calculusxy):

Sorry I meant the measures of variability: Lower Quartile = 4 Upper Quartile = 150 Interquartile Range = 146 Range = 128

OpenStudy (calculusxy):

OpenStudy (calculusxy):

Am I correct? Or are you still doing the problem? Or other?

jimthompson5910 (jim_thompson5910):

oh gotcha, ok so I get this mean = 92.14 (approximate) median = 62 mode = None range = 128 min = 350 max = 163 Q1 = 410 Q3 = 150 IQR = 109 I used geogebra to calculate all that but you can use any piece of software really. You can also do so by hand.

jimthompson5910 (jim_thompson5910):

and yeah, the mean absolute deviation is 51.9 (approximate)

OpenStudy (calculusxy):

I am confused with the minimum, lower quartile, upper quartile, and the IQR.

jimthompson5910 (jim_thompson5910):

the min is the smallest value

jimthompson5910 (jim_thompson5910):

Q1 = lower quartile Q3 = upper quartile IQR = Q3 - Q1

OpenStudy (calculusxy):

But think about it.

OpenStudy (calculusxy):

How can the minimum be 350 and the maximum be 163?

OpenStudy (calculusxy):

@jim_thompson5910

jimthompson5910 (jim_thompson5910):

oh wow, my bad lol I mixed the two up

jimthompson5910 (jim_thompson5910):

and somehow geogebra also messed up . I need to check more closely

jimthompson5910 (jim_thompson5910):

min = 35 max = 163

OpenStudy (calculusxy):

@jim_thompson5910

OpenStudy (calculusxy):

Sorry I disappeared...

jimthompson5910 (jim_thompson5910):

that's fine
