Unit A1: Optimising physiological performance



Unit 6.1Statistical AnalysisKey learning intention (KLI)Learn how to calculate and manipulate data using graphic calculators and excel.Success criteriaI can calculate the mean and standard deviation for a set of data and explain what the coefficient of variation and t-test tells us about that data.ResourcesP138-143, Scientific calculator, Computer with excelKey wordsMean, standard deviation, error bars, coefficient of variance, t-test, causal relationship4674870120650003745865220041006.1.1.Outline that error bars are a graphical representation of the variability of data6.1.2.Calculate the mean and standard deviation of a set of valuesWorld leading long jumps by men and women over the past 50 yearsMenWomenMeanStandard deviation05942400What % of data lies within 1 Standard deviationsWhat % of data lies within 2 Standard deviations231584537465006.1.3.State what standard deviation is. Standard deviation is…554197625908000A________________ standard deviation indicates that the data is clustered closely around the mean value. Conversely, a ________________ standard deviation indicates a wider spread around the mean.6.1.4.State how SD is useful for comparing the means and the spread of data between two or more samples-85090-51435Track and field challenge. We are going to compare the performances of all members of the class.You have one practice go, and then you must record your next 10 jumps.We will collect everybody’s results, calculate their mean and SD and discuss what the results may mean. Use error bars to display this information.Have fun!00Track and field challenge.

Graph the data using error bars.00Stick your excel table here with your long jump scores and calculated mean and SD. Graph the data using error bars.6.1.5.Outline the meaning of co-efficient of varianceCoefficient of variation (V)The ratio of the standard deviation to the mean expressed as a percentage.V= 100 x SDMeanNow calculate the coefficient of variation for each member of the class for their mean long jump distance. Copy and paste the table below.What do the results show?6.1.6.Deduce the significance of the difference between two sets of data using calculated values for t and the appropriate tables.t-testIt can be used to determine if two sets of data are significantly different from each other. Two-tailed t-testPaired t-testUnpaired t-test5565471126365006.1.7.Explain that the existence of a correlation does not establish that there is a causal relationship between two variables.
