Now select the region in the table where the results go. Type the LINEST function or paste using the function wizard with the correct data columns for y-variables and x-variables and the values True for the 3rd and 4th arguments which correspond to intercept and stats respectively.
The intercept flag can be False if you want your line to go through the origin. The stats flag should be turned on to get the stats you want. Press Control-Shift-Return when ready. There will be some cells that show an error code because there is no output for that cell. I don't know how to get rid of the error messages. If they really bug you use one of the macros below. That will ask you for a range of y-values and a range of x-values.
If you data columns have labels at the top, select those labels too and check the Labels checkbox in the dialog window.

Select an output range with plenty of space to the right and below. There is quite a bit of output from this macro. Check any plots you want to be created.

Then press OK. The output appears in sections: Your instructor can tell you More about what these items mean.

Enter the ranges for the Dependent Y variable and then the Independent X variables. When you press OK a new worksheet will open with lots of useful results. This includes all from the Data Analysis Toolpak which your instructor can explain plus a few more like the formula for the best line and residual values. It can also be performed using regression analysis by introducing a binary dependent variable for each group.
Both require continuous dependent variables. A nice description of the problem can be found at http: That will ask you for the data range and whether the data is grouped by column or row.
Also select an output range with some room to the right and below. The output looks like that on website referred to above and your instructor can give you details. Enter the data range. A new worksheet is created with the results. The results are essentially identical to that of the Data Analysis Toolpak.
Spreadsheet Macros: Histogram Here we wish to take a list of data for one variable and divide it into "bins", counting how many datapoints lie in each bin. For example, to use the Bins , , the column should be entered as: Bin 5 10 15 More Now you are ready for creating the histogram. The expression should be: A, B2: B5 with A1: Your hand-made table and chart will automatically be updated when you change the data. Regression Here we wish to find the best linear fit for a single dependent variable Y as a function of one or more independent variables X. To perform data analysis on the remainder of the worksheets, recalculate the analysis tool for each worksheet.
