WGU C797 FINAL EVALUATION & RESULTS
CONFIRMED PASS GUARANTEED 2026.
◍ Formula for coefficient of determination Answer:squaring the
Pearson's r value (r^2)
◍ What is a correlation? Answer:A Specific type of relationship that
is measured mathematically to represent the strength and direction of
relationships
◍ Correlation coefficient is graphed using what kind of graph?>
Answer:Scatter plot
◍ On a scatter plot, if there is a positive correlation, then as the x
increases the y will Answer:increase
◍ On a scatter plot, if there is a negative aka inverse correlation, then
as X increases Y will Answer:decrease
◍ Pearson's correlation coefficient only measures Answer:linearity
◍ Spearman's Correlation Coefficient measures Answer:monotonic
relationship -relationships that are always in the same direction.
,◍ Pearson's Correlation coefficient is a parametric test that allows
researchers to determine if there is a relationship b/w to variables of
what kind of measurement scale? Answer:Interval or ration
◍ Spearman's Correlation coefficient is a non-parametric test that
what kind of data? Answer:Ordinal or interval/ratio
◍ Pearson and Spearman's correlation coefficient are both denoted by
___. And range from ___ to ___ Answer:r; -1 to 1
◍ Perfect positive correlation coefficient is equal to Answer:1
◍ Perfect negative correlation coefficient is equal to Answer:-
1
◍ The coefficient of determination range Answer:0-1
◍ If the coefficient of determination range is 1 or close to 1, what
does that mean about the variance Answer:There more the variance is
shared
◍ The higher the variance shared the... Answer:more significant the
relationship
◍ 1st step in creating a Pearson's Correlation Coefficient
Answer:Form a null and alternative hypothesis
, ◍ Second step when creating a Pearson's Correlation Coefficient
Answer:define the significance values a-level and find the critical
value
◍ To be able to say that a statistically significant association between
the two variables exists, the computed value of the correlation
coefficient (r) must exceed the: Answer:the critical value for the α-
level that is chosen
◍ critical value is the value obtained from Answer:is the value of r
that is obtained from the table of critical values for the Pearson
correlation coefficient.
◍ What does the critical value mean? Answer:the value at which the
probability of obtaining that value is at or below the a-level
◍ How to fine the degree of freedom for r Answer:number of
participants(n) - 2 ( n-2) example 10 participants means the degree of
freedom is 8
◍ How to get the critical value Answer:You make up your a value
(example 0.05), then you find the degree of freedom (n-2) example
10-2=8. Then go to the chart, always use the 2 tailed test, go to 8 on
the left, find 0.05 on the top and find where they meet (example:
0.632)
