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.HSS.ID.C.8

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

• interpolate

points where a line crosses the x-axis and y-axis

• slope

• tangent and normal

• causal relationship

• intercepts

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

A graph with points plotted to show a possible relationship between two sets of data.
