Standard Deviation and a Bell Shaped Curve. Bozeman Biology Video on Standard Deviation. Standard deviation measures the spread or the variation in the data. 68% of the individuals are within 1 standard deviation . Introduction. All transmitted signals will contain some rate of error (>0%). Popular error control methods include:. Parity bits (add a 1 or 0 to the end of each seven bits). Longitudinal redundancy checking (LRC). Standard Deviation. Standard Deviation – measure . how spread out the data is from the mean. Lower standard deviation:. Data is . closer to the mean. Greater likelihood that the independent variable is causing the changes in the dependent variable. 7 In such instances, to reduce the uncertainty stemming from such dramatic reductions in statistical power, the computation of standard errors of alpha would enable researchers to determine whether or
