 * State that error bars are a graphical representation of the variability of data.
 * Calculate the mean and standard deviation of a set of values.
 * State that the term standard deviation is used to summarize the spread of values around the mean, and that 68% of the values fall within one standard deviation of the mean.
 * Explain how the standard deviation is useful for comparing the means and the spread of data between two or more samples.
 * Deduce the significance of the difference between two sets of data using calculated values for t and the appropriate tables.
 * Explain that the existence of a correlation does not establish that there is a causal relationship between two variables.
