  • Approximations 
    Kruger, P.S. (Paul Stephanus), 1944- (2008-08-29)
    The calculation of individual probability terms from a Binomial distribution may cause some computational difficulties for large values of n. The same may be true for the Poisson distribution for large values of the mean. ...
  • Construction of a stem-and-leaf plot from sample data 
    Kruger, P.S. (Paul Stephanus), 1944- (2008-08-12)
    A Stem-and-Leaf plot, is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution. Unlike histograms, stem-and-leaf plots retain the ...
  • The construction of box-plots 
    Kruger, P.S. (Paul Stephanus), 1944- (2008-08-29)
    A Box-Plot is a visual display of the summary statistics associated with a process on a single graphic. It is a convenient way to compare the statistical characteristics of different processes and to monitor a process for ...
  • The construction of histograms from sample data 
    Kruger, P.S. (Paul Stephanus), 1944- (2008-07-16)
    A Histogram is one of the most important tools of descriptive statistics. It provides a Graphical estimation of the Distribution and Statistical Characteristics of the underlying stochastic process from which the sample ...
  • Data sets, descriptive measures, histograms and data patterns 
    Kruger, P.S. (Paul Stephanus), 1944- (2008-08-29)
    One of the principle purposes of mathematical statistics is to provide tools by which the existence of a "pattern" in a data set may be detected and quantified, or classified. Descriptive statistical measures and graphical ...
  • Hypotheses testing : P-values 
    Kruger, P.S. (Paul Stephanus), 1944- (2008-08-12)
    In statistical hypothesis testing, the P-value is the probability of obtaining a value of the test statistic at least as extreme as the one that was actually observed, given that the null hypothesis is true. The fact that ...
  • Hypotheses testing : sensitivity 
    Kruger, P.S. (Paul Stephanus), 1944- (2008-08-07)
  • The logical union of events 
    Kruger, P.S. (Paul Stephanus), 1944- (2008-08-29)
    The logical operations of a Union and an Intersection of several events defined on an event space is often required in the calculation of the probability for compound events. The concepts of Mutual Exclusiveness and Mutual ...
