The numerical characteristics of the population

A number that represents a portion of the sample

an x or y

actual values of variable

Population is all

sample is specific

Categorical data

Numerical answers

Data that you can count

Data that you can measure

a sample of individuals from the population chosen in such a way that every group of individuals has an equaled chance of selection

select every nth individual from the population

splits the available population into small groups in which the same number of subjects are selected from each group

all members of a certain group are selected

a survey of all individuals in a population

Favors one result over another

how different the answers are

changing sampling methods

take larger samples

the number of times something occurs

frequency divided by total number

Adding the relative frequency to your stopping point

A method of applying treatments to a group and recording the data

researchers collect data based on what is seen or heard

Active data collection involving a treatment imposed on the subjects being studied

the participants in the study

The specific condition being imposed on the subjects the condition can be a combination of factors

the variable that the experimenter is altering by administering the treatment

the variable that we are measuring in the subjects

Any variable that could have in effect on the results

A dummy treatment with no active ingredients

Often patients will respond to any treatment

One of the two groups should be receiving either a placebo or an existing treatment

Subjects are randomly placed in treatment or control group

A study where subjects do not know which treatment they are receiving

A study where the subjects and the people administering the treatment do not know who receives each treatment

An experiment testing the effectiveness of a medical treatment on human patients

Best for Discrete or Continuous Data

Best to use with Continuous Data

Best to use with large amounts of any quantitative data

A number that divides the order

x=k(n+1)
