Please help me. It's my birthday but my dad says I have to do this assignment first so please help me.

Compare standard deviation and residual analysis.

Describe when/how each are used.

Answer 1

standard deviation is a quantity calculated to indicate the extent of deviation for a group as a whole.

Residual analysis is used to assess the appropriateness of a linear regression model by defining residuals and examining the residual plot graphs.
