1. a researcher conducts a within-subjects design and notes that scores increased at each level of the factor for all participants. based on this description, does this test have high power to detect the effect?

a.

no, because participant responding was inconsistent.

b.

no, because participant responding was consistent.

c.

yes, because participant responding was inconsistent.

d.

yes, because participant responding was consistent.

2. the following results is reported for a one-way within-subjects anova: f(2, 27) = 3.55, p < .05, η2p (partial eta squared) = -0.14. which value in the summary cannot be correct?

a.

the test statistic

b.

the p value

c.

the effect size

d.

the degrees of freedom

3. the alpha level for each hypothesis test made on the same set of data is called

a.

testwise alpha

b.

experimentwise alpha

c.

pairwise comparison

d.

the bonferroni procedure

4. among the descriptions about the bonferroni test below, which one is false?

a.

the bonferroni test is an appropriate post hoc test following a significant one-way within-subjects anova.

b.

with a small number of comparisons, the bonferroni test is an appropriate post hoc test following a significant one-way within-subjects anova.

c.

the bonferroni test controls for experimentwise alpha.

d.

the bonferroni test controls for testwise alpha

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

when functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. these won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. small sets of points are generally the simplest sorts of relations, so your book starts with those.

step-by-step explanation:

state the domain and range of the following relation. is the relation a function?

{(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

the above list of points, being a relationship between certain x's and certain y's, is a relation. the domain is all the x-values, and the range is all the y-values. to give the domain and the range, i just list the values without duplication:

domain: {2, 3, 4, 6}

range: {–3, –1, 3, 6}

(it is customary to list these values in numerical order, but it is not required. sets are called "unordered lists", so you can list the numbers in any order you feel like. just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)

while the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

note that all i had to do to check whether the relation was a function was to look for duplicate x-values. if you find any duplicate x-values, then the different y-values mean that you do not have a function. remember: for a relation to be a function, each x-value has to go to one, and only one, y-value.

state the domain and range of the following relation. is the relation a function?

{(–3, 5), (–2, 5), (–1, 5), (0, 5), (1, 5), (2, 5)}

i'll just list the x-values for the domain and the y-values for the range:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

where are the graphs?
