You are enjoying a relaxing hike when the answer to a problem you have been
struggling with for days and had put aside suddenly revealed itself. This method
of knowing is called the_____________. - ANSWER Method of Intuition
This method of knowing uses both reasoning and intuition but relies on objective
assessments. Hypothesis testing is an essential step in the use of this method.
This method of knowing is called: - ANSWER Scientific Method
This method of knowing uses reason alone to arrive at knowledge, often using
syllogisms in which a major premise and a minor premise are followed by a
conclusion. For example:
All participants in the study were at least 18 years old.
Andy was a participant in the study.
Andy is at least 18 years old.
This method of knowing is called _____________. - ANSWER Rationalism
A researcher is exploring the effect of classroom environments on learning. Two
identical PSY230 courses are being taught by the researcher. One is taught in a
room with glass walls which allows students to see persons walking past, the
other is in a similarly configured room with opaque walls. Students' learning is
assessed at the end of the semester with a comprehensive examination. The
independent variable in this scenario is the: _______. - ANSWER type of wall

dependent variable in this scenario is the: _______. - ANSWER exam score
Observational studies can be used to determine causality. (T/F) - ANSWER False
True experiments, which include manipulation of the independent variable,
measurement of the dependent variable, and random sampling, can be used to
determine causality. (T/F) - ANSWER True
, _______________ statistics are concerned with techniques that are used to
describe or characterize the obtained data. - ANSWER Descriptive
Later in the course, we will make inferences about populations based on sample
data. This one of the most frequent uses of statistics. This group of statistical
methods are called ________________ statistics. - ANSWER Inferential
The book lists two important benefits of the use of random sampling. They
include.. - ANSWER Random sampling allows the laws of probability to be
applied to our data.
Random sampling helps achieve a sample that is representative of the
population.
A statistic calculated on population data is known as __________________________.
- ANSWER a parameter
A researcher is interested in the effects of sleep on performance on scores on
an examination in basic statistics. 100 students who completed the PSY 230
course during the previous semester were randomly assigned either to a group
receiving 8 hours of sleep or a group receiving 4 hours of sleep. All of students
resided either in Dorm A or Dorm B. Following the night of either 8 or 4 hours of
sleep, participants completed a 100 item statistics exam. An independent-
samples t test was used to determine whether there was a difference on
examination scores between the two groups.
The independent variable in this scenario is: - ANSWER Amount of sleep
