Question

In a study , the average age of the male candidates who were affected in a disease, was 38.20 whereas the average age of the female subjects was calculated to 34.976 with the standard deviation of 156.91 and 116.16 in male and female respectively..

What conclusion can I draw from this finding?

Answer 1

$$V _ {\text {male}} = \frac {\sigma}{\bar {x}} = \frac {156,91}{38,2} = 4,1 \ (410 \%)$$ $$V _ {\text{female}} = \frac {\sigma}{\bar {x}} = \frac {116,11}{34,976} = 3,32 \ (332 \%)$$

Critical limit: $V_{\text{limit}} = 33\%$,

$$V _ {\text{male}} > V _ {\text{limit}}$$ $$V _ {\text{female}} > V _ {\text{limit}}$$

Answer:

$V_{\text{male.female}} > 33\%$, this mean that statistical collection, which is studied is not homogeneous, so results can't be used as reliable
