Step Hypothesis Testing Process

Question 1
What is the main goal of ANOVA?
The main goal of ANOVA is to determine if there is any significant difference between the mean of three or mean
independent groups.
Question 2
The main difference between a t-test & an ANOVA is that t-tests are limited to ______
treatments whereas ANOVA can compare _______ or more treatments (the same answer fits for
both blanks).
Group of answer choices
unlimited
three
two
only one
Question 3
The number of variables assessed when conducting an ANOVA is determined by the researcher.
Group of answer choices
True
False
Question 4
What is the definition of analysis?
Analysis would refer to detail examination of given data in order to derive
useful information.

Question 5
The _______ variable is the one manipulated by the researcher.
Group of answer choices
independent
dependent
Question 6
The symbols used in an ANOVA problem are standard & universal throughout the statistics
world. No matter what resource you review, the symbols always remain the same.
Group of answer choices
True
False
Question 7
Variance is a measure of variability that indicates how far scores in a distribution vary from the
mean. There are two main variances evaluated for ANOVA problems. These variances
are variance & variance.
Question 8
Why is it that the alternative hypothesis for an ANOVA design is stated as "at least one
population mean" is different from the other? What is the significance of not providing the
specific means being compared?
The alternative hypothesis is framed in this manner since if even one group has a different
mean, then it would imply that all groups do not the same/similar means. If specific means
have to be compared, then there are other tools which can accomplish the same and
ANOVA would not be required.
Question 9
For an independent measures design ANOVA problem, the symbol representing the number of
scores in each treatment condition is [x].

Question 10
The basic 4-step Hypothesis Testing Process is the same for ANOVA as it is for the other
measures.
Group of answer choices
True
False
Question 11
The subscripts accompanying values within the ANOVA testing procedure are designed to
identify which data set that particular value is associated with.
Group of answer choices
True
False
Question 12
For both independent & repeated ANOVA measures designs, the symbol 'SS' stands for [x].
