What is three elements to an experiment?
100
Count or measure of an entire population
What is census
100
consists of attributes, labels and noncommercial entries
What is Qualitative data
100
True or false- if dealing with two genders, Nominal measuring will be used.
What is true?
100
To collect data and make a decision based upon it
What is the main goal of any statistical study?
200
when an experimenter cannot tell the difference in effects of different factors
What is a confounding variable?
200
while they provide complete information, they are too costly and difficult
What are the positives and negatives of a census?
200
Consists of numerical measurements and counts
What is Quantitative data
200
level that would most likely be used when dealing with first, second, and third place
What is ordinal
200
Even if you aren't the one to develop a statistical study, you have to
What is Interpret the data and apply it accordingly
300
Prevents a placebo effect.
What is blinding?
300
Preventing biased data
What is making sure it is a representative of a population
300
determines what statistical procedures are possible
What does a data’s nature determine?
300
True or false- Measuring differences in temperature is ordinal.
What is false?
300
type of study that the observer does NOT influence the result at all.
What is observational
400
Technique where the subjects do not know whether they are receiving a treatment or placebo
What is blinding
400
the difference between the results of a sample and those of a population
What is sampling error
400
True or false- Your shoe size is a collection of quantitative data
Is it True?
400
measurements that have equal distance along the scale but are also classified due to size
What is ratio
400
the observant also does in an experiment that they wouldn't do in an observational study.
What is purposefully does something to change an element and possibly alter the data?
500
When a subject reacts favorably to a placebo the it has actually been given a fake treatment.
What is placebo effect
500
unlike a random sample, a simple random sample is only for those samples of the same size
What is the difference between a Random sample and a simple random sample?
500
Level that is the most precise.
What is Nominal.
500
First you must identify the variables of interest and the population of the study, then for the last step you should check for any possible errors.
