Standard deviation can be difficult to interpret as a single number on its own. Basically‚ a small standard deviation means that the values in a statistical data set are close to the mean of the data set‚ on average‚ and a large standard deviation means that the values in the data set are farther away from the mean‚ on average. The standard deviation measures how concentrated the data are around the mean; the more concentrated‚ the smaller the standard deviation. A small standard deviation can

STANDARD COSTS Setting a budget is never easy as it involves predicting the future and therefore uncertainty. The process is not about getting the budget absolutely right; it is about not getting it too wrong. This budget process may be applied to most revenue budgets that deal with income and costs‚ but there is also a requirement to produce a capital budget that covers the purchase‚ sale and replacement of fixed assets.

Standard Deviation (continued) L.O.: To find the mean and standard deviation from a frequency table. The formula for the standard deviation of a set of data is [pic] Recap question A sample of 60 matchboxes gave the following results for the variable x (the number of matches in a box): [pic]. Calculate the mean and standard deviation for x. Introductory example for finding the mean and standard deviation for a table: The table shows the number of children living
