Answer:
D. Mean absolute deviation
Step-by-step explanation:
Median gives us : 159
Range gives us: 680 - 127 = 553
mean gives us :
127+137+159+188+680 = 1291
1291 / 5
= 258.2
MAD gives us the mean deviation (avg change from the mean):
mean
= 258.2
258.2 - 127 =131.2
258.2 - 137 =121.2
258.2 - 159 =99.2
258.2 - 188 =70.2
680 - 258.2
=421.8
Find the mean of the variances:
70.2+99.2+121.2+131.2+421.8 = 843.6
843.6 / 5
= 168.72
Mad = 258.2 +- 168.72
It is the fourth round and this is because in round one Katie has 200 and Jenny will have 300.In round two katie will have 400 and Jennifer will have 500.In round 3 Katie will have 600 and and jennifer will have 800.I
