      Applies basic algebra and statistical techniques and formulas (e.g., measures of central tendency, standard deviation) to calculate data. Understands and can select and use advanced statistical and quantitative techniques and principles (e.g., random sampling, multiple regression, factor analysis, analysis of variances, and discriminate ...

      Determine the number of divisions for any test load by dividing the value of the mass standard being applied by the minimum division indicated by the scale. For example, if the scale has a minimum division of 0.1 g and a 1500 g mass standard is applied, the test load is equal to 15 000 divisions (1500/0.1).

      Also, think of stock returns: if two stocks have a mean of 10% and one has a huge standard deviation and one has a small standard deviation. If you did not want to risk having big losses or big gains in any one year, you would want the stock return with the smaller standard deviation, such as, for example, 9%, 11%, 8%, 10.5%, 10%, 9.75% ...

      The standard deviation is a measure of the range of random variables. It is usually denoted . Formally, the standard deviation is the square root of the mean of the differences between the values and the mean of the values. ...

      A low standard deviation indicates that the data points tend to be very close to the mean, whereas high standard deviation indicates that the data are spread out over a large range of values. In addition to expressing the variability of a population, standard deviation is commonly used to measure confidence in statistical conclusions.

      The risk of the portfolio as measured by the standard deviation is reduced when the covariance is reduced. If the correlation is less than +1.0, the standard deviation of the portfolio always will be less than the weighted average standard deviations of the individual assets. 8.

      A team that is consistently good in most categories will also have a low standard deviation and will therefore end up winning more than losing. A team with a high standard deviation might be the type of team that scores a lot (strong offense) but gets scored on a lot too (weak defense); or vice versa, might have a poor offense, but compensate ...

      The standard deviation is the average variation of the data values from the mean of the values and is the most commonly used measure of variation. Note that the values for the standard deviation are different for a sample and a population.

      In multiple regression, we say that the simple slope of the IV on the DV changes depending on the level of the moderator, and with continuous moderators we generally compare “high” levels of the moderator (+1 standard deviation above the mean) to “low” levels (-1 SD below the mean).
