, The ________ is/are the entire group of individuals or population
items being studied
The ______ is/are a subset of the population that is being sample
studied
A _____ is a numerical measurement describing some statistic
characteristic of a sample
Suppose that a researcher is interested in the average sample, statistic
standardized test score for fifth graders in a local school
district. The fifth graders at a specific school would
comprise a ___________ and their average test score
would be a ___________.
A ________________ variable counts or measures quantitative
something and has numeric values.
Can a qualitative variable have values that are numeric? Yes; it is possible to have numeric variables that do not count or measure anything,
Why or why not? and, as a result, are qualitative rather than quantitative.
A quantitative variable that has a finite or countable discrete
number of values is called _______.
A quantitative variable that has an infinite number of continuous
possible values that are not countable is called _______.
A variable is at the _______ level of measurement if it ordinal
allows for the values of the variable to be arranged in a
specific order but the differences between values either
cannot be determined or are meaningless.
In a television advertisement, a company called "Waist experiment
Away" claimed the workout program on their set of DVDs
would help people lose weight more than any other DVD
workout program. To test this claim, an independent
company, called "Slim Down," selected one other DVD
program. They then randomly assigned half the volunteers
to the Waist Away program and the other half to the Slim
Down program. Each participant was weighed before they
started the program and then regularly participated in their
assigned program for one month. After one month, each
participant was weighed again. The percent of weight lost
was recorded for each person, where negative values
indicated a weight gain. What type of study was
performed?
Do people walk faster in an airport when they are observational study
departing (getting on a plane) or after they have arrived
(getting off a plane)? An interested passenger watched a
random sample of people departing and a random sample
of people arriving and measured the walking speed (in feet
per minute) of each. What type of study design is being
performed?
