Question

Adam has the scatterplot shown for his data set, where snowfall is measured in inches, and he is trying to describe the line of best fit. Which choice correctly describes the line of best fit?

Answer 1

Answer:

The best fit line is a regression line explaining relationship between dependent & independent variables, minimising the residual differences between observed values & actual values of dependent variable.

Step-by-step explanation:

Regression is a statistical process that explains relationship between dependent variable & independent variable(s). Scatter plot depicts the regression relationship between the variables in a graphical form.

Scatterplot showing snowfall measured in inches : is a graphical depiction of - regression relationship between snowfall as a dependent variable with its explanatory (independent) variables ; like temperature, humidity , other climate & weather factors etc.

The line of best fit would be a regression line (scatterplot), which describes the relationship of snowfall with its above mentioned explanatory variables, in such a way that the estimated value of snowfall is closest possible tothe actual values of snowfall (i.e their difference is minimum).
