Which of the following is symbol of variance of a sample

Mean, Standard deviation and shape are characteristics of

• Confiedance interval

• Variance

• A random distribution

The goal of ____________ is to form a conclusion about a population parameter from sample statistics taken from the population

• Descriptive stat

• Inferential Stat

• Sampliing distribution

Assumption of homogeneity of variance can be expressed as

A study which subjects from two (or more) samples are paired (matched) by the experimenter on an extraneous variables

• matched pair investigation

• Repeat measure design

• Matched Subjects design

_________ is probability of rejecting a false null hypothesis

• T-test

• Power of test

• critical value

Recognize the formula

• Computation formula for t for independent means

• Computation formula for t for dependent means

• Computation formula for t for correlation coefficient

Point Estimation is...

• when we calculate a range of

  values within which it appears reasonable that the parameter lies

• when we desire a single value which appears reasonable for the parameter

• when we desire a single value as an estimate of the population value

this is formula for...

• confidence interval computation with .90

• confidence interval computation with .99

• confidence interval computation with .95

this is formula for...

• Total sum of squares

• Sum of squares within the group

• Sum of squares Between the group
