If you already have your data on a spreadsheet, then you will be able to copy it from the spreadsheet and paste it into the text area. Before you copy and paste, make sure your top row has the names of the variables whose values run down each column. For example, "mint," "year," and "mass" each designate the values that run down their respective columns.
Make sure that all of your rows are the same length, and that all of your columns are same length. In other words, your spreadsheet must be rectangular, with no missing cells in any row or column.
Next, make sure that the individual cells in the spreadsheet have no spaces in them. For example, some of the pennies in our older data sample, from the jar, were minted in San Francisco. We had to enter the name as "San_Francisco" to keep the program from mistaking the space between words as a separation of cells for two mints that did not exist: "San" and "Francisco."
Once you paste the spreadsheeted data into the text area, it might not look exactly aligned.
Don't try to fix the misalignment. If you have followed the previous instruction on format, the program should still build a control panel correctly.
You can also paste data from the text area back into a spreadsheet. Then you can add to an existing sample in the ease of your own spreadsheeting program.
