30318-8 DistributionThere is a variety of different types of distribution, but the most well-known is“normal distribution,” which is essential for performing statistical calculations.Normal distribution is a symmetrical distribution centered on the greatest occur-rences of mean data (highest frequency), with the frequency decreasing as youmove away from the center. Poisson distribution, geometric distribution, andvarious other distribution shapes are also used, depending on the data type.Certain trends can be determined once the distribution shape is determined. Youcan calculate the probability of data taken from a distribution being less than aspecific value.For example, distribution can be used to calculate the yield rate when manufactur-ing some product. Once a value is established as the criteria, you can calculatenormal probability density when estimating what percent of the products meet thecriteria. Conversely, a success rate target (80% for example) is set up as thehypothesis, and normal distribution is used to estimate the proportion of theproducts will reach this value.Normal probability density calculates the probability that data taken from anormal distribution is less than a specific value.Normal distribution probability calculates the probability of normal distributiondata falling between two specific values.Inverse cumulative normal distribution calculates a value that represents thelocation within a normal distribution for a specific cumulative probability.Student- t probability density calculates the probability that data taken from a tdistribution is less than a specific value.Student- t distribution probability calculates the probability of t distribution datafalling between two specific values.Like t distribution, distribution probability can also be calculated for chi-square, F,binomial, Poisson, and geometric distributions.While the statistical data list is on the display, press 5 (DIST) to display thedistribution menu, which contains the following items.• {NORM}/{t}/{CHI}/{F}/{BINM}/{POISN}/{GEO} ... {normal}/{t}/{χ2}/{F}/{binomial}/{Poisson}/{geometric} distributionAbout data type specificationFor some types of distribution you can select data type using the following menu.• {List}/{Var} ... specifies {list data}/{parameter data} |
