Try the ten year moving average-what do you think now about your linear projection?
Hint: show the equation by right-clicking the trendline itself and select Format trendline. Do you think it is getting warmer? How hot will the average be in 2050? (You have to calculate this.
Perturbation is the difference from the beginning of 1900 in this case.) Let's quickly discuss this with the following spreadsheet: (download this from the web to your disk space): L05_climate.xls (Mean Tempurature perturbations for the US (in degree Celsius).

Curve fitting using the Add Trendline option when right clicking a data series point in a chartĪll you have to do is to right-click a data point within a chart then select Add TrendLine. Later, we will utilize an Excel tool called Solver, whereby we can fit a data set to more general functional forms, i.e., more freedom than a straight line, exponential, logarithmic, etc. First, we'll explore Excel's built-in "Trend-line" option, where we can add trend lines to data sets after a chart has been generated. Today, we will experiment with curve fitting using Excel. I will try to provide some more tutorials, but I am expecting that you are reading the assignments and asking questions in class when we do the demos! As the semester carries on, you will be doing more and more of the work with out such detailed instructions. However, you now have enough tools under your belt to tackle problems with out the step by step instructions. So far, the Excel assignments have been with a fair bit of guidance, even with step by step recipes.
