are used to examine relationships between two or more quantitative/numerical variables. They measure the strength and direction of a relationship between variables.
Are used to check the relationship between variables or values?
Correlation
1 Page 2 • A correlation exists between two variables when one of them is related to the other in some way. The Pearson linear correlation coefficient is a measure of the strength of the linear relationship between two variables.
What are the four main types of relationships between variables?
- a linear or non-linear relationship,
- a positive (direct) or negative (inverse) relationship,
- the concentration or spread of data points,
- the presence of outliers.
What are the 4 types of relationships?
There are four basic types of relationships:
family relationships, friendships, acquaintanceships, and romantic relationships

What is the relationship between the variables?
The statistical relationship between two variables is referred to as their
correlation
. A correlation could be positive, meaning both variables move in the same direction, or negative, meaning that when one variable's value increases, the other variables' values decrease.
How do you know if two variables are associated?
Association between two variables means the values of one variable relate in some way to the values of the other. Association is usually measured by
correlation
for two continuous variables and by cross tabulation and a Chi-square test for two categorical variables.
How do you analyze the relationship between variables?
When analyzing many variables, scatter plots and
correlation coefficients
can quickly uncover patterns and reduce a large amount of data to a subset of interesting relationships. Correlation describes the strength of relationship between two variables. A correlation coefficient ranges from -1 to +1.
What is a correlation relationship?

a measure or degree of relationship between two variables

Which of the following indicates the strongest relationship?
The strongest linear relationship is indicated by
a correlation coefficient of -1 or 1
. The weakest linear relationship is indicated by a correlation coefficient equal to 0. A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
What are the 3 types of correlation?
