Document Summary
Gaussian distribution: gaussian distribution: an ideal smooth curve that is a result of repeated experimentation, as results tend to cluster about the average value, mean: the sum of the measured values divided by n, the number of measurements. The standard deviation measures the width of the gaussian curve. If the known answer does not lie within the 95% confidence interval, then the two methods give different results. Comparison of standard deviation with the f test. F test: tells us whether two standard deviations are significantly different from each other. o o o o. If f-calculated < f-table, use the first t-calculated equation. If f-calculated > f-table, use the second t-calculated equation. If f-calculated > f-table, then the difference is significant. If g-calculated is greater than g on p. 83, the questionable point should be discarded. Equation of a straight line: y = mx + b, where m is the slope and b is the y- intercept.
