In this paper, we present an example of multiple-solution problems in statistics involving a set of non-traditional dice. In particular, we consider the exact probability mass distribution for the sum of face values. Four different ways of solving the problem are discussed. The solutions span ...
This example shows how to examine similarities and dissimilarities of observations or objects using cluster analysis in Statistics and Machine Learning Toolbox™.
It illustrates sample size calculations for a simple problem, then shows how to use the sampsizepwr function to compute power and sample size for two more realistic problems. Finally, it illustrates the use of Statistics and Machine Learning Toolbox™ functions to compute the required sample ...
We first specified quotation marks indicating that we want to specify a character string. Afterwards, we just pasted a numeric value that was unexpected for R. Let’s solve this problem… Example 2: Fix the Error – unexpected numeric constant in X ...
Give an example of inferential statistics.Answer and Explanation: Whenever you measure a part of a population, and estimate some value about the rest of the population, you are using inferential stastics. A phone survey would be a good example of inferential statistics....
Provide two examples of a two-factor ANOVA. Identify the grouping and test variables of each example. ANOVA: Analysis of variance (ANOVA) enables statistics practitioners to compare the data for more than two different groups, within each of one or two factors—ma...

The empirical rule is often used in statistics for forecasting final outcomes. After calculating thestandard deviationand before collecting complete data, this rule can be used as a rough estimate of the outcome of the impending data to be collected and analyzed. ...
Financial delinquencies damage a person's credit history and score, making it difficult to obtain new credit, rent a home or a car, and other aspects of finances. The U.S. has a consumer debt problem with consumers carrying high levels of debt, increasing the chances of delinquencies. It ...
