Answer:
[tex]3.5[/tex] - written in [tex]2/14/2021[/tex]
Step-by-step explanation:
#1st Step: First, let's find the mean: [tex]\frac{8+5+12+15}{4}=\frac{40}{4} =10[/tex]
#2nd Step: Next, let's find the distance each data point is from the mean:
Data Point | Distance from the mean
[tex]8[/tex] | [tex]10-8=2[/tex]
[tex]5[/tex] | [tex]10-5=5[/tex]
[tex]12[/tex] | [tex]12-10=2[/tex]
[tex]15[/tex] | [tex]15-10=5[/tex]
#3rd Step: The mean absolute deviation (MAD) is the mean of the distances from the mean: [tex]\frac{2+5+2+5}{4} =\frac{14}{4} =3.5[/tex] alligators
So this is how I found the answer, [tex]3.5[/tex]. (Happy Valentines Day!)
