Mean
7 days
add them up and divide by 7
50+56+52+46+48+42+38=332
divide that by 7
47.428 about
distance each is from the mean
50 is 2.572 from it
56 is 8.572 from it
52 is 4.572 from it
46 is 1.428 from it
48 is 0.562 from it
42 is 5.428 from it
38 is 9.428 from it
add those and average them
(2.572+8.572+4.572+1.428+0.562+5.428+9.428)/7=4.652
absolute deviation is 4.652 aprox
