Occurs when an experimenter cannot tell the difference between the effects of different factors on a variable that are outside the scope of the experiment or study

these are the statistics you find when you meet a new set of numerical data?
mean, standard deviation
200
The collection of all outcomes, responses, measurements, or counts that are of interest
What is a population?
200
Involves using sample data to draw conclusions about a population

What is Q1 or the first quartile?

300

A range of values surrounding the sample mean within which one can be reasonably certain the population mean resides.

500

A controlled treatment is applied to part of a sample and is compared to a part of the sample that does not receive the treatment and responses are observed

What is an Experiment?

500

Occurs when people choose to be part of a study.

What is voluntary response bias?

500
Produces answers to specific questions with a level of confidence that the answer is correct. (using stats to predict the future)
