Simple Regression Basics

A simple regression analysis is done using made up data of ice cream sales related to high temperature for a period of twenty days. A fitted line plot is first constructed, the slope and intercept are interpreted, then I run a regression, clean up the output, and interpret a few more regression statistics.

I don't have the data analysis option under my Data tab on Excel. I have Excel 2010. Is there something I am not doing right?

lower R square value is better or the higher?

[kruegerrand]

I got a number value where it says temp on the regression analysis, what does that mean?

What is the procedure of creating regression equation like, y = k*x^.5?
here, i have to find the value of " k ", in the equation from of y = k*x^.5

the data set of x are; 3870, 2740, 2150
the data set of y are; 290, 280, 210

How can this be done when for example you have sales data at every half day but temp data every day. Can you correlate both when you have different data size but same number of days?

wow dude, slow it down a bit. If you are teaching or demonstrating something for others, there's no need to race through it.
