level of significance is 0.1 and the sample size is 15 is [ Ans: ]
7.785

variances taken from normal populations with equal variances is [
Ans: ] an F distribution
The symbol used for the variance of the sample is [ Ans: ] s^2
Guru01 - Stuvia
The sampling distribution used when making inferences about a
single population's variance is [ Ans: ] a chi-square distribution
Which of the following has a chi-square distribution? [ Ans: ] (n-
1)s^2/o^2
The symbol used for the variance of the population is [ Ans: ] o^2
In factorial designs, the response produced when the treatments
of one factor interact with the treatments of another in influencing
the response variable is known as [ Ans: ] interaction
an ANOVA procedure is used for data that was obtained from
four sample groups each comprised of five observations. The
degrees of freedom for the critical value of F are [ Ans: ] 3 and
16
In order to determine whether or not the means of two
populations are equal, [ Ans: ] either a t test or an analysis of
variance can be performed
The mean square is the sum of squares divided by [ Ans: ] its
corresponding degrees of freedom

An experimental design that permits statistical conclusions about
two or more factors is a [ Ans: ] factorial design
The variable of interest in an ANOVA procedure is called [ Ans: ]
a factor
The ANOVA procedure is a statistical approach for determining
whether or not [ Ans: ] the means of two or more populations
are equal
A term that means the same as the term "variable" in an ANOVA
procedure is [ Ans: ] factor
The F ratio in a completely randomized ANOVA is the ratio of [
Ans: ] MSTR/MSE

In an analysis of variance, one estimate of o^2 is based upon the
differences between the treatment means and the [ Ans: ]
overall sample mean
Guru01 - Stuvia
The critical F value with 6 numerator and 60 denominator degrees
of freedom at a=.05 is [ Ans: ] 2.25
When an analysis of variance is performed on samples drawn from
k populations, the mean square between treatments (MTSR) is [
Ans: ] SSTR/(k-1)
The process of allocating the total sum of squares and degrees of
freedom is called [ Ans: ] partitioning
In an analysis of variance where the total sample size for the
experiment is nT and the number of populations is K, the mean
square within treatments is [ Ans: ] SSE/(nT-K)
Which of the following is NOT a required assumption for the
analysis of variance? [ Ans: ] Populations have equal means
The number of times each experimental condition is observed in a
factorial design is known as [ Ans: ] replication
in the ANOVA, treatment refers to [ Ans: ] different levels of a
factor
