Term
Are operationalized definitions the
same that may be used in the field or
used by a researcher in prior studies?
Definition
No, They don't have to match
Term
Statistical analysis is the nuts and
bolts worth that gives
researchers……?
Definition
the information needed to determine the success and failure
Term

process that drawing conclusions is
the point at which what happens?
Definition
Yes
Term
Does level of measurement influence
what kind of statistical analysis can
be performed?
Definition
Yes
Term
The lowest level of data in terms of
levels of measurement is?
Definition
Nominal
Term
What level of data has a true zero?
Definition
Ratio
Term
Why is the mean VERY important to
statistical analyses?
Definition
It is the basis of many of the formulas for higher order statistical procedures
Term
Is the mode the frequency of the
number that occurs most often in the
distribution?
Definition
No, it is the category or class
Term
Is it possible for there to be more than
1 mode is a distribution?
Definition
Yes
Term
A standard normal curve is
mesokurtic?
Definition
Yes
Term
Is the closer of the values of skewness
and kurtosis to 0, the better the
distribution approaches to a normal
curve?
Definition
Yes
Term
Does a bivariate table display the
frequencies of two variables separately
or together?
Definition
Together
Term
In an ordinal level table, should the
row headings be arranged in
descending order?
Definition
Yes
Term
How do you create a bivariate table in
SPSS?
Definition
Analyze-Descriptives-Crosstabs
Term
Can a nominal level table provide information about the direction of association between two variables?
Definition
No determination can be made concerning the direction of the data because nominal data cannot be ordered
Term
Is the ordering of categories in a
nominal level table as important as
in an ordinal level table?
Definition
No, its not important in a nominal table
Term
What is the null hypothesis of chisquare test?
Definition
No significant relationship between two variables
Term
How are degrees of freedom calculated
for a chi-square test?
Definition
Numbers of Rows minus one times the number of columns minus 1
Term
Is chi-square heavily influenced by
sample size?
Definition
Yes
Term
What is descriptive analysis?
Definition
describes the data
Term
What is statistical analysis?
Definition
clearest method of examining numbers
Term
What do inferential statistics allow you
to do?
Definition
Allows us to see if there is a relationship
Term
What questions does theory ask?
Definition
What is the point?, What does it mean?, Why are things this way?
Term
Research methods are about
testing…?
Definition
Theory
Term
What is the first step in the process of
scientific inquiry?
Definition
Observation and Inquisitiveness
Term
How many variable(s) does an
univariate analysis deal with at a
time?
Definition
One
Term
What is the median?
Definition
50th percentile of the distribution
Term
In a bivariate table, the dependent
variable is often in the….?
Definition
Dependent: Rows
Independent: Columns
Term
A bivariate table has 4 columns and 3
rows, it is a……?
Definition
4 X 3 table
Term
The cell frequency is usually denoted
by what symbol?
Definition
N(little ij) N (little rc)
Term
The level of data in the table, and thus
the table itself, is an important
consideration in analysis because the
level of data will determine what?
Definition
The type of analysis you're going to do
Term
The row percentage of a cell is
calculated by dividing the cell
frequency with…?
Definition
column total, row total, or N then multiply by 100
Term
Why are bivariate tables seldom used
for interval and ratio data?
Definition
Because they get messy/confusing to use
Term
In SPSS, in order to arrange the
categories in descending order, you
need to check the box marked
descending after you click what?
Definition
Format Button
Term
With ordinal level data, the goal is
to….
Definition
Predict the rank order of pairs of scores instead of the modal value
Term
What is Somers’d?
Definition
Asymmetric ordinal level measure of association
Term
Ordinal level data that is fully ordered
and interval level data that is not
normally distributed is generally
analyzed using?
Definition
Spearmans Rho
Term

association at the nominal level is?
Definition
Lambda
Term
