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
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
True experiments, which include manipulation of the independent variable,
measurement of the dependent variable, and random sampling, can be used to
determine causality - ANSWER True
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
dependent variable in this scenario is the: _______ - ANSWER score on the
comprehensive examination

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 Method of Rationalism

describe or characterize the obtained data. - ANSWER Descriptive
Observational studies can be used to determine causality. - ANSWER False
, 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
This scale has categories for units. - ANSWER Nominal
This type of variable theoretically can have an infinite number of values between
adjacent units on the scale. - ANSWER Continuous
In statistical notation, N stands for ________________. - ANSWER The total number
of subjects or scores

This scale has equal intervals between adjacent units but does not have an
absolute zero. - ANSWER Interval
This scale has equal intervals between adjacent units and does have an absolute
zero. - ANSWER Ratio
The Celsius scale of temperature is an example of a variable measured on the
________________ scale - ANSWER Interval
In the formula below, which operation would be performed first?
(X + Y) * 3 - 1/2 - ANSWER The operation enclosed in parentheses
It is standard practice to carry all intermediate calculations to _________ decimal
place(s) further than will be reported in the final answer. - ANSWER two or more
The real limits of a continuous variable are those values that are above and
below the recorded value by _____ of the smallest measuring unit of the scale -
ANSWER one-half
One way to differentiate a bar graph from a histogram is that
____________________. - ANSWER the bars touch on a histogram
A relative frequency distribution indicates
_____________________________________. - ANSWER the proportion of the total
number of scores that occurs in each interval
