... to show how long (in hours and minutes) are they in class each day. At Jerome Horwitz Elementary, the day starts at 8:30 and ends at 3:30. Students have 40 minutes for lunch and 20 minutes for recess. Draw a picture to show long they are in class each day. (If the school year is 180 days long, write ...

Alternatively students could be presented with Problems 2 and 3 and asked to explore the variations presented in the paper and then find situations which produce sp ...

... Example 2: A technologist is developing a new method for processing a food material. It is known that for best quality, it is important to control moisture content in the final product. So, as one part of determining the practicality of the new method, the technologist must estimate the variability ...

Lecture 5. Time to failure - Failure intensity [4mm] Measures

... Failure intensity λ(s) describes variability of life lengths in a population of components, objects or human beings. Extensive statistical studies are needed to estimate λ(s). More often, observed information is not sufficient to determine the failure intensity. Sometimes one has only access to the ...

As an illustration, we will look at an analysis of variance example for which we want to test the so-called “normality assumption” that states that the within group deviations (i.e., the “residuals”) are normally distributed. The data are from Abdi (1987, p. 93ff.) and correspond to memory scores ob ...

History of statistics

The History of statistics can be said to start around 1749 although, over time, there have been changes to the interpretation of the word statistics. In early times, the meaning was restricted to information about states. This was later extended to include all collections of information of all types, and later still it was extended to include the analysis and interpretation of such data. In modern terms, ""statistics"" means both sets of collected information, as in national accounts and temperature records, and analytical work which requires statistical inference.Statistical activities are often associated with models expressed using probabilities, and require probability theory for them to be put on a firm theoretical basis: see History of probability.A number of statistical concepts have had an important impact on a wide range of sciences. These include the design of experiments and approaches to statistical inference such as Bayesian inference, each of which can be considered to have their own sequence in the development of the ideas underlying modern statistics.
