Collection of data and information

Process of steps to collect and analyze

Collects non-numerical data

Analysis of numerical data and form conclusions

Identify the cause and effect

A group is kept under observation

Seeks to finds relationships between independent and dependent variables

Randomized Experiment

Does not involve manipulation of variables to yield result

Describe the sample and seek to answer the question “what” rather than “why”

Determine the relationship between two or more variables

Can be measured, described, controlled or manipulated in a study

Numbers from data that can be added, subtracted, multiplied, divided

Represented in numbers but cannot be added, subtracted, multiplied, divided

Variables that may be constant, controlled or manipulated in an experiment

Countable Variables

Infinite Values

Numbers are used gor ranking/order

Variables that are affected when manipulating the independent Variables

Influence both the dependent and Independent Variables

Not manipulated nor change

Variables that are manipulated to affect the outcome of an experiment

There is no “absolute zero”

There is “absolute zero”

Only two possible answer

Number are used for naming or identification
