Question

Below is the mean income and standard deviation for 2 communities. Tell me what the difference is in these 2 communities. Based on the data only, how might these 2 communities be different:

Community A: mean income = $20,100; standard deviation = $10,022

Community B: mean income = $21,000; standard deviation = $1,035

Answer 1

## Q ) Below is the mean income and standard deviation for 2 communities. Tell me what the difference is in these 2 communities. Based on the data only, how might these 2 communities be different:

Community A: mean income = $20,100; standard deviation = $10,022

Community B: mean income = $21,000; standard deviation = $1,035

Answer :

1) comparison of mean :

here mean for community A is less than community B ,

that is estimate is more for community B than community A , hence we can say that community B is better than

community A . generally average more consider it good .

2) comparison of standard deviation :

here standard deviation for community A is more than community for B

we know that when we compare standard deviation less standard deviation is better than large standard deviation . if less standard deviation then there is less variability then there might have less error . and large standard deviation there is more variability then there might have large error . hence generally less standard deviation is better or good than large standard deviation .  

we can say community income for B is good than community income for A .
