When sample sizes are equal, MSWithin is figured by
 
  A) summing the population variance estimates figured within each group and dividing by the total number of participants (over all groups).
  B) summing the population variance estimates figured within each group and dividing this sum by the number of groups.
  C) multiplying the within-groups sum of squares (SSWithin) by the size of each sample (n).
  D) dividing the within-groups sum of squares (SSWithin) by the size of each sample (n).

Question 2

In an analysis of variance, if the null hypothesis is false, then
 
  A) the variation between sample means reflects the variation within the populations as well as the variation between the population means.
  B) the within-groups variance is significantly larger than the between-groups variance.
  C) the variance within each sample is larger than if the null hypothesis were true.
  D) the variance between sample means is no greater than the variance within the population with the largest variance.

Did you know?

Though methadone is often used to treat dependency on other opioids, the drug itself can be abused. Crushing or snorting methadone can achieve the opiate "rush" desired by addicts. Improper use such as these can lead to a dangerous dependency on methadone. This drug now accounts for nearly one-third of opioid-related deaths.

Did you know?

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.

Did you know?

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.

The B-complex vitamins and vitamin C are not stored in the body and must be replaced each day.
