Understanding Relationships in Data

a connection between two variables where as one variable increases, the other variable also increases

• negative relationship

• positive relationship

• causal relationship

• correlation coefficient

CCSS.HSF-LE.A.1B

the data is tightly clustered around a best fit line and the correlation coefficient (r) is close to 1 or -1

• strong relationship

• medium effect (goodness of fit)

• foreign key

• correlation coefficient

a change in one of the variables directly causes a change in the other variable

• causal relationship

• correlation

• ability to foresee harm

• dependent variable

the method of estimating a value within a given data set by using the known values around i

• extrapolate

• nterpose

• inference

• interpolate

to estimate a value that falls outside the range of known data points by extending the pattern or trend observed within the existing data

• excoriate

• interpolate

• extrapolate

• exonerate

• scatter plot

• weak relationship

Tags

CCSS.HSF-LE.A.1B

an equation that describes a relationship between two variables where the change between them is constant

• interpolate

• linear model

• global surrogate model

• channel

Tags

CCSS.8.F.A.3

the data points on a scatterplot are widely dispersed and do not closely follow a line

• correlation coefficient

• weak relationship

• weak entity

• strong relationship
