Data that comes in form of numbers.
True or False:
Numerical data

What do experimental studies typically involve?
A treatment or condition that has been manipulated by the researcher.
What is a survey?
A data collection tool or instruments that researchers use to collect numerical data.
A measured or manipulated quantity or trait, broadly classified into two types: independent and dependent.

Describe inferential statistics
Statistical analyses used to infer information about a population using data collected from a sample.
An inferential statistics that examines the relationship between one or more predictor and outcome variables.
Regression
A set of data collected or selected from a population.
A sample
How is the quantitative data represented?
In tables, charts, etc.
Describes a quantifiable relationships between variables, including the extent to which variables change together.
This is the description of what study?
Correlational studies
True.
The goal of quantitative research
Identify and explain reality as it exists empirically.
What do the sample sizes do?
Represent the population.
True or false:
Descriptive studies are the data collected without changing or manipulating the environment.
TRUE
What is factor analysis?
A method of combining variables into a single measure.
Main characteristic of quantitative data.
Use of numerical data
If you have a representative sample, how are the results generalized?
To an entire population.
Inferential statistics that estimate the influence of one or more measures on an outcome.
Prediction statistics
Define effect size.
A measure that quantifies the difference between two or more measures.
