HSCI 345 Exam 2 (latest update 2025-
2026) questions and 100% correct answers
[Grade A]
ANOVA - correct answer analysis of variance
Analysis of Variance - correct answer allows for comparison of three or more sample
means
true or false: if a research design involves the use of an independent variable that has
more than two groups, then a t-test is not statistically appropriate. - correct answer
true
number of independent variables - correct answer -one independent variable in a
one-way ANOVA
-more than one independent variable in a factorial ANOVA
type of independent variable (s) - correct answer -independent groups: subjects are
tested under only one level of the independent variable(s)
ex. gender, group membership, etc.
-repeated measures: subjects are tested under all levels (repeatedly) of the
independent variable(s)
, HSCI 345 Exam 2 (latest update 2025-
2026) questions and 100% correct answers
[Grade A]
ex. any data collected repeatedly for a person
true or false: all factorial ANOVAs are labeled based upon the number of levels in
each independent variable - correct answer true
true or false: different types of factorial designers allow for an almost infinite number
of possible ANOVAs - correct answer true
rationale for using a one-way independent groups ANOVA - correct answer a one-
way independent groups ANOVA is appropriate because:
-there is only one independent variable with 3 levels
-participants are tested under only 1 level of the independent variable
-there is only 1 dependent variable, and the variable is at lest an interval or ratio level
of measurement
basic assumptions of the one-way independent groups ANOVA - correct answer -the
independent variable must be nominal in nature and participants must be tested
independently (independence)
