What is a spreadsheet?

spreadsheet is a computer program that turns your computer screen into a smart piece of paper. It removes much of the grunt work associated with repetitive calculations and lets you easily see the results of your work. We have chosen to use spreadsheets in the physics labs, because they reduce the amount of time needed to look at and understand the data taken in the labs. Traditionally accountants have used spreadsheets to do bookkeeping and budgets, but they make outstanding tools for scientists as well. With a spreadsheet, we can enter raw data, manipulate it and plot it all with a few simple commands. They are especially useful because of their built in ability to plot data.

How to plot a graph in Excel?

For example, suppose you want to plot sin(x) vs x. To do this, you will need to have some x-values that we can take the sine of (if you did not already do this when working through the previous part). Start by entering the label “X” into cell D1. Next enter 0 into cell D2. Then in D3 enter =D2+0.3. Next copy this formula from D2, D3, ... D20. Next enter the label “Sin(X)” into cell E1. Now in E2, enter = SIN(D2). Copy this formula to cells E2,...E20 (see Figure 2). To plot this data, go to the top of the spreadsheet and click on the Insert tab (see Figure 2). Now use your mouse to point at and select cells D1 to D20 and cells E1 to E20 (just click on cell D1, hold the left mouse button down as you drag the mouse to cell E20, and then release the mouse button). Then look for the section of the menu at the top of the spreadsheet that says Charts and click on Scatter (see the note below about why you should never use anything other than Scatter for plotting). You will be presented with a sub-menu of different types of scatter plots (just points, just lines, lines and points, etc.), choose any one of these by clicking on it. You should now see a plot and notice that the menu at the top of the spreadsheet has changed. Now click on the Quick Layout menu and try selecting Layout #10, which has a pretty nice format. All of your plots should have labels on the x and y-axes. In this case, Layout #10 just has default labels that say “Axis Title”. To change the axes labels, just click on them and type in X for the x-axis label and Sin(x) for the y-axis label.

How to do least squares in Excel?

The spreadsheet allows you to do least square fits to data. To see how this works, make some data that follows a linear trend by copying the same numbers you have in column D into column F and label them with T for time. Next enter =2*F2+1 into cell G2 and copy this down into cells G3 to G20. Excel has built-in functions that use a least square fit to determine the slope and intercept that best fit a set of data. To determine the slope, go to H2, and enter
