QUESTION
If two groups differ by
12
12
12
and the common MAD is
3
3
3
, what is the separation in MADs?
QUESTION
Find the separation multiple if
x
ˉ
A
=
18
\bar{x}_A=18
x
ˉ
A
=
18
,
x
ˉ
B
=
12
\bar{x}_B=12
x
ˉ
B
=
12
, and
MAD
=
2
\text{MAD}=2
MAD
=
2
.
QUESTION
Identify the correct conclusion if
∣
Δ
∣
=
2
|\Delta|=2
∣Δ∣
=
2
and
MAD
=
8
\text{MAD}=8
MAD
=
8
for two groups.

ANSWER
Strong overlap because
k
=
2
8
=
0.25
k=\frac{2}{8}=0.25
k
=
8
2
=
0.25
is small.
k
=
2
8
=
0.25
k=\frac{2}{8}=0.25
k
=
8
2
=
0.25
is close to 0, indicating minimal separation.
