Answer:
MAD = 2
Step-by-step explanation:
<u><em>First We'll find the mean of data</em></u>
Mean =
Mean = 4
<u><em>Then, we'll find absolute deviation</em></u>
=> |4-3| = 1
=> |4-2| = 2
=> |4-1| = 3
=> |4-1| = 3
=> |4-3| = 1
<em><u>Now, taking the mean of these absolute deviations:</u></em>
MAD =
MAD =
MAD = 2
*The minimum is 39.*
the lowest recorded temperature is 39 so this is correct
*The lower quartile (Q1) is 44.*
first lets list the numbers from small to large
39, 43, 44, 44, 45, 49, 49, 50, 51,
now we need to find the median of 39, 43, 44 and 44
43.5 is the Q1 of our statics not 44
The median is 45.
again lets list the numbers from small to large
39, 43, 44, 44, 45, 49, 49, 50, 51,
median is the middle number so this is correct
The maximum is 51.
the biggest number is 51 therefore this is correct
