You have designed an experiment to see what effect singing has on learning sign
language. As part of the study, you are gathering pretest and posttest data. You're
afraid that the pretest might have an effect on the experiment. How would you
best contend with this?
Chi-square
ANOVA
Solomon four-group design
Multiple regression ---------CORRECT ANSWER-----------------Solomon four-group
design
In the process of studying the Japanese language, Chelsea discovers that the more
time she spends practicing, the better she gets. What are the independent and
the dependent variables?
Chelsea's progress in learning the Japanese language is the independent variable,
and time is the dependent variable
Time is the independent variable, and Chelsea's progress in learning the Japanese
language is the dependent variable
Both time and Chelsea's progress in learning the Japanese language are
dependent variables
, Both time and Chelsea's progress in learning the Japanese language are
independent variables ---------CORRECT ANSWER-----------------Time is the
independent variable, and Chelsea's progress in learning the Japanese language is
the dependent variable
In this case, the amount of time Chelsea spends learning the Japanese language
is the independent variable, and her progress is the dependent variable. The
more time she spends practicing, the better she gets at the language. Time is
the variable that causes an influence on her proficiency in the language.
A value of r=-0.90 indicates that there is a:
Weak, positive relationship between x and y
Strong, negative relationship between x and y
Strong, positive relationship between x and y
Weak, negative relationship between x and y ---------CORRECT ANSWER--------------
---Strong, negative relationship between x and y
Since r is a negative value here, it indicates that there is a negative relationship
between x and y. The value r is considerably close to r=-1, meaning that the
relationship is a strong one. A scatter plot with r=-0.90 looks like a straight line
going from the top left to the bottom right.
The difference between the variance and standard deviation is that:
The variance is the mean minus standard deviation squared
The variance is the square root of the median minus the standard deviation
,The variance is the sum of squares divided by N
The variance is the sum of the squares of itself and the standard deviation ---------
CORRECT ANSWER-----------------The variance is the sum of squares divided by N
Which of the following is an independent variable?
The passage of time, in years
Maturity
Height
Weight ---------CORRECT ANSWER-----------------The passage of time, in years
The passage of time, in years, is an independent variable. Time is always an
independent variable, whether in seconds, minutes, hours, or years. Height,
weight, and maturity are all dependent variables because they are all under the
influence of another variable, such as time.
How do you find the median of a set with an even number of items?
A set with an even number of items does not have a median
Find the average of the two middle numbers
The two middle numbers are both medians
The larger of the two middle numbers is the median ---------CORRECT ANSWER----
-------------Find the average of the two middle numbers
When there is an even number of items in a set, the median is the average of
the two middle numbers.
, The factors that are the most important in test instrument selection are:
Power and speed testing
Test-retest construction
Concrete and pre-operational
Validity and reliability ---------CORRECT ANSWER-----------------Validity and
reliability
Before you can determine the standard deviation, you must calculate which of the
following?
Median
Mode
Variance
Mean ---------CORRECT ANSWER-----------------Mean
Which of these clients most need a referral to a physician?
A 25 year old female who has relapsed using crack cocaine following a
miscarriage
A 53 year old woman grieving for a longer than normal period for her deceased
husband
A 47 year old man with a history of depression who suddenly exhibits bouts of
rage
