Science of collecting, organizing, summarizing, and analyzing information to draw conclusions or answer questions

Provides procedure in data collection, presentation, organization, and interpretation to have meaningful idea

Information referred to

Factual information used as a basis for reasoning, discussion, or calculation

Basically consist of organizing and summarizing data

Describe data through numerical summaries, tables, and graphs

Logical process that involves generalizing from a sample to the population from which sample was selected

Inferential statistics is also known as?

Consists of all the members of the group which you want to draw conclusions

Portion or part of a population selected

Numerical index describing characteristic of population

Numerical index describing characteristic of sample

Data that come from original source and intended to answer specific research question

Data taken from previously recorded data

Characteristic of object, people that does not vary

Characteristic of object, people that csn take different values

Variables that yield categorical responses

Words of codes that represent class or category

Variables that take on numerical values representing amount or quantity

These numerical values should answer the question how much or how many

Weight of person

Financial statements

Variable that can stand alone

Extremely reliant on other variables. Cannot stand alone

Quantitative variable that could take on whole numbers

Quantitative variable that could take on decimal numbers

Categorical data where categories have no rankings or order

Categorical data where categories have rankings/order

Numerical data that has no absolute value

Numerical data that has an absolute value

Process of choosing individuals from a population to a sample

You are using an objective chance mechanism to obtain a sample

The probability of selection for a sample is known

There is an equal chance of selection for your samples

There is a system or pattern in choosing your sample

You are dividing the population to non overlapping groups called strata then choosing sample from each strata

You divide the population into strata then normally select a group and choose all samples within that group

Sampling method where no objective chance mechanism is used instead the sample is chosen by convenience

We are choosing the samples conveniently available

We identify a specific criteria or qualification before an individual can be a sample

Non-probability counterpart of strs

We are relying on samples to obtain more sample

You are asking your sample to volunteer themselves to be part of your study

It describes the number of observations for each possible value of a variable

It presents the frequency and percentage for each possible value of a variable

Is the number of values in a specific class of frequency distribution or the number of occurrences of specific class in a data set

Can be computed by the frequency of a class divided by the total number of values multiplied by 100

Commonly referred to as an average or a single value that represents a data set

Its purpose is to locate the center of a data set

The most frequently used measure of central tendency

It is the only common measure in which all values play an equal role meaning to determine its values you would need to consider all the values of any given data set

What is the formula for mean

Symbol used to represent the mean of a sample

Symbol used to denote the mean of a population

Is the midpoint of the data array

Middle most value

Data set arranged in order

True or false: if n is odd the median is the middle ranked value

True or false: if n is even the median is the average of the two middle ranked value

Is the value in a data set that appears most frequently

A data set only has one value that occurs

The data set has two values with the same greatest frequency both values are considered the mode

The data set have more than two modes

Cases when data set values have the same number frequency

The mode is found by locating...

Spread of data values from the average

How is range computed

Describes the difference between data values and the mean

Squared measure

Squared of SD

Describing the location of a value on the data array

Split the data set in 4 equal parts

Split the data array in 10 equal parts

Split the data array in 100 equal parts
