Population is organized in groups. Groups Examples: Schools, Communities, Companies. A random sample of the groups is chosen. All the members of the groups would be surveyed.

sample

Using this sampling technique, requires that the population be divided into groups. These groups are called Strata.

sample

A measured value that can change.

None

This occurs when surveys are not returned – thereby influencing the results.

Bias

Employs Checkmarks for selection

Question

a study that considers individuals from different groups at the same time.

Study

A statement or question that your project will answer or discuss.

None

Can include a decimal, rational numbers –4/67 or 67

Number

Respondent uses own words – allows for a wide variety of possibilities that are sometimes difficult to interpret.

Question

a random defined number which provides a measure of scale.

None

Facilitates the storage and retrieval of a wide range of data

None

Samples from which the selected elements cannot be reintroduced into the population.

sample

this occurs when the chosen sample does not accurately represent the population.

Bias

factors in the sampling method that influence the result. – poor question design – interviewer tone and attitude

Bias

an unintended influence when gathering data from a sample.

None

A study that considers individuals over a long period of time.

Study

Can be raw data or cumulative information depicted on a table.

None

Requires that all selections are equally likely and all combonation of selections are equally likely.

sample

data that can be described using whole numbers.

None

Definition

Answer

Hint

can’t be a fraction of a number, a percentage, or have a decimal.

Number

Data collected by you.

None

variables that can be measured numerically.

None

information that is gathered about an entire population.

None

variables that cannot be described numerically.

None

the respondent must choose from a given list of responses. These responses are easily analyzed.

Question

A visual display use in brainstorming to show relationships → Flow Charts

None

Population be divided into groups. A random sample of groups is chosen and then a random sample of members of the chosen group is taken.

sample

Asking someone to rate one particular thing.

Question

This occurs when one type of respondent is overrepresented because groupings of different sizes are polled equally. – Overrepresentation

Bias

Numbers which can continue forever. ex- Pi

Numer

a conclusion that can be made about a population, which is based on a sample.

None

data that are only measurable with real numbers

None

Data that is collected over a period of time.

None

Used when sampling a fixed percent of the population

sample

a word of phrase sought over the Internet

None

Uses a scale – 1 to 4 for example

Question

Data collected from other sources.

None

Used to store data (textual and numerical) in rows and column called “cells”. Can manipulate this data using formulas
