  1. Statistics Using a Sharp EL-W531 Calculator Mode ALPHA Activates “green” statistic functions Comma Data enter key Mean r “correlation coefficient” Standard deviation

  2. Standard deviation (σ) using a Sharp EL-531 1. Put calculator into statistics mode for data with 1 variable : 3. Get the standard deviation Find the standard deviation of the following frequency table Mode ALPHA Activates “green” statistic functions Comma • 2. Enter the data (“x-value, frequency”) Data enter key Standard deviation • Standard Deviation = 0.836

  3. Correlation (r) using a Sharp EL-531 1. Put calculator into statistics mode for data with 2 variables : 3. Get the correlation Find the correlation between the following bi-variate data Mode ALPHA Activates “green” statistic functions Comma • 2. Enter the data (“x-values, y-values”) Data enter key r “correlation coefficient” • Correlation: r = -1
