The standard deviation is a measure of how close together a set of data is grouped. In\u00a0Chapter 2 of your text, Kozak (2014) stated:<\/p>\n<p>\u201cIn general a \u201csmall\u201d standard deviation means the data is close together (more consistent) and a \u201clarge\u201d standard deviation means the data is spread out (less consistent). Sometimes you want consistent data and sometimes you don\u2019t. As an example if you are making bolts, you want to lengths to be very consistent so you want a small standard deviation. If you are administering a test to see who can be a pilot, you want a large standard deviation so you can tell who are the good pilots and who are the bad ones.\u201d\u00a0(p. 89).<\/p>\n<p><strong>Example Situations Involving Pilots<\/strong><\/p>\n<p>A <strong>large standard deviation<\/strong>\u00a0tells us that there is a lot of <strong>variability<\/strong>\u00a0in the scores; that is, the distribution of scores is spread out and not clustered around\u00a0the mean.\u00a0As Kozak (2104) has stated, when assessing potential pilots, we may want a large standard deviation, so that we can\u00a0<strong>differentiate<\/strong> between candidates; that is, we can determine who would be good pilots and those who would not be good pilots. Since a large standard deviation\u00a0tells us that there is a lot of <strong>variability<\/strong> in the scores, candidates, who\u00a0would be good pilots, would have\u00a0scores far above the mean, while those who would not be good pilots\u00a0would have scores\u00a0far\u00a0below the mean. Thus, only the &#8220;top&#8221; candidates would be selected to be pilots.<\/p>\n<p>A <strong>small standard deviation<\/strong> tells us that there is not a lot of variability in a distribution of scores; that is, the scores are <strong>very consistent (similar)<\/strong> and close to the mean. Using our pilot example, a small standard deviation is desirable, when considering aircraft landing distances. If there is not enough distance when landing, the aircraft could undershoot the runway; that is, land short of the runway. On the other hand, if there is too much distance, the aircraft can overshoot the runway; that is, the aircraft does not stop before the end of the runway. Both undershooting and\u00a0overshooting runways could result in injuries and\/or fatalities. Thus, it is important that pilots\u00a0have consistent accurate landing\u00a0distances. Specifically, over a number of landings, the distances would, on average, be appropriate to the runway length with little variation among the distances.<\/p>\n<p>Now think about how this might apply in your chosen field and answer both of the following questions:<\/p>\n<ul>\n<li>What is an example of when you would want consistent data and, therefore, a small standard deviation?<\/li>\n<li>What is an example of when you might want a large standard deviation?
