There are two common ways you can statistically describe uncertainty in your measurements. The mean, or average, of a group of values describes a middle point, or central tendency, about which data points vary.

In this case, the temperature of **the metal is the** independent variable being manipulated by the researcher and the amount of energy absorbed is the dependent variable being recorded. However, though you can say that the means of the data you collected at 20 and 0 degrees are different, you can't say for certain the true energy values are different.

The sample standard deviation will always be greater than the population standard deviation when they are calculated for the same dataset. We can also say the same of the impact energy at 100 degrees from 0 degrees. Standard Error Excel Formula However, remember that the standard error will decrease by the square root of N, therefore it may take quite a few measurements to decrease the standard error. How To Calculate Standard Error In Excel 2013 The +/- value is the standard error and expresses how confident you are that the mean value (1.4) represents the true value of the impact energy.
