Complete Solutions
1-tailed significance Correct Answers when researchers choose
this they are pretty confident that the outcome will result in
going one direction (higher or lower). This is also more
powerful.
2-tailed significance Correct Answers the direction can go
either way, higher or lower
Abstract Correct Answers tells what the article/journal is going
to be about. The author uses presents the background, method,
results, and conclusion. The purpose of the research study is
clearly stated in the abstract.
Assumptions Correct Answers must be met to make influences
about the findings of a study and for a "r" to be used. 1.Must be
representative of the population, 2. Variables must have a
normal distribution, 3. Variances are equal in both groups, 4. X
and Y must form a linear relationship.
Assumptions (rules) Correct Answers requirements that must
be met for using the statistical test, but that cannot be absolutely
proven.
Background (Review of Literature) Correct Answers This is an
introduction to the researchers' literature search and a review of
literature or background material about the problem, issue, or
topic of interest. Usually documents previous research that
,relates to the area of the current study. needs to be in the last 10
years
Bar chart Correct Answers Can be used for nominal and
ordinal measurements. One of the most common ways to display

number in some interval
Control Group Correct Answers group that does not receive the
treatment
, Convenience Sample Correct Answers sample where subjects
are selected because they are available and willing to participate
in the study
Correlation Coefficient Correct Answers the "r"; a measure of
the linear correlation between two variables X and Y.
Correlation Matrix Correct Answers a table of correlation
coefficients, level of significances, and sample size listed
horizontally or vertically
Cumulative percent Correct Answers adds the percent of each
subject with a total of 100% represented for the valid percent or
the subjects who actually entered their final statistics exam
score.
Curvilinear Relationship Correct Answers a relationship
between two variables that does not meet the assumption of
linearity.
Degrees of Freedom (df) Correct Answers the number of
values in the final calculation
Descriptive Correct Answers finding the probability of an
occurrence from a sample
Descriptive Statistics Correct Answers includes procedures for
summarizing data, describing averages or typical values, and
describing variation within a data set.
