Question

The Lakeview track coach recorded how long it took each member on the Lakeview track team to run 200 m. The Harbor City track coach recorded how long it took each member on the Harbor City track team to run 200 m.

What conclusion can be drawn, based on the value of the means-to-MAD ratio?

Track team Mean MAD
Lakeview 25.8 0.4
Harbor City 24.2 0.5

Answer 1

A.
The Lakeview and Harbor City track teams’ 200 m times are about the same.

B.
The Harbor City track team’s 200 m times are greater than the Lakeview team’s 200 m times.

C.
The Harbor City track team’s 200 m times are less than the Lakeview team’s 200 m times.

D.
No conclusions can be drawn.

Answer 2

ignore the diamond question marks

Answer 3

and lakeviews mean is 25.8 and MAD is 0.4

Answer 6

what was the answer..?

Answer 7

@jim_thompson5910 do you know this answer?

Answer 8

here is how you calculate the means-to-MAD ratio

Step 1) subtract the means (larger - smaller)

Step 2) Divide the result in step 1 by the larger MAD value

Answer 9

the last one is kinda confusing to me can you demonstrate it plz. If it is no trouble

Answer 10

what is the difference in the means?

Answer 11

0.6

Answer 12

try again

25.8 - 24.2 = ??

Answer 13

oops sorry 1.6

Answer 14

now divide that by the larger MAD value

Answer 15

3.2

Answer 16

In your notes somewhere you should have these 3 rules or something like it:


a) if the means-to-MAD ratio is 1 or less, then the 2 distributions are similar

b) if the means-to-MAD ratio is between 1 and 2.5, then the 2 distributions are somewhat similar (but not as strong as rule a)

c) if the means-to-MAD ratio is larger than 2.5, then the 2 distributions are different

Answer 17

So ITs C?

Answer 19

:) yep its C
