Do the standard deviations satisfy the guidelines for the use of ANOVA? No, because the largest standard deviation is less than twice the smallest standard deviation. No, because the largest standard deviation is more than twice the smallest standard deviation. Yes, because the largest standard deviation is less than twice the smallest standard deviation. Yes, because the largest standard deviation is more than twice the smallest standard deviation.

No, because the largest standard deviation is more than twice the smallest standard deviation.

Step-by-step explanation:

Okay, so the standard deviation for each of the sample is given as;

NHES II study = 2.486, NHANES II study = 2.408 and NHANES study = 5.851.

In order to determine whether the standard deviations satisfy the guidelines for the use of ANOVA, one of the conditions for anova for sample standard deviations must be considered that is;

'' the value of the sample standard deviations should not be times two of the smallest standard deviation."

In which if we have; highest sample standard deviations / smallest standard deviation < 2, Then, population variance is equal.

if you need , reply with more info. u.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
