Available in PDF, EPUB and Kindle. Book excerpt: Louisiana's current statistically based specification system was initiated in 1967. This system was based upon contractor quality control and department acceptance testing using known variability concepts. A materials data base was also initiated at that time to archive materials test results and information. Since inception of the data base and system, major changes have been incorporated into the standard specifications. Further, there have been advances in equipment and operational control devices that can further reduce construction and test variation.

Available in PDF, EPUB and Kindle. Book excerpt: The statistically oriented specification for bituminous concrete production reviewed in this report was used as a basis for acceptance of more than one million tons of bituminous concrete in 1970. Data obtained from this system were analyzed for gradation and asphalt content for such comparisons as how well the production average matched the stated job mix formula; how well the variability of lot means matched the variability measure the limits were based on; and how well the range method of predicting the standard deviation matched the actual standard deviation. It was found that the 1970 bituminous concrete production was consistent with that of 1967, on which the specification was based; that the range method can predict standard deviations accurately and can be used on a lot by lot basis; and that, although the present tolerances are working well, there are some areas where improvements are possible.

Download or read book Appendix E Mean Direction and Mean Absolute Deviation written by Veronika Jones and published by . This book was released on 2009 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mean directional and mean absolute deviations are statistics that can be used to summarize and check the balance of JAR data. The JAR data are analyzed separately for each product and each attribute. The mean directional deviation is the average signed difference of the ratings from the Just About Right value. On a 5-point JAR scale, the mean directional ranges from 2 to +2 (Just Right =0). Scores that are closer to 2 indicate that respondents thought that attribute was Too Low. Scores that are closer to +2 indicate that respondents thought that the attribute was Too High. The mean direction deviation is a simple shift of the mean, covered in Appendix D. The mean absolute deviation summarizes the spread of the ratings about the Just About Right value. On a 5-point scale, the mean absolute deviation ranges from 0, when all judgments are Just About Right to +2, when all judgments are at one or the other extreme end of the scale. Unlike percent Just-Right scores, absolute deviations can be calculated for each individual and the mean absolute deviation analyzed by any of the standard parametric statistical procedures. The mean absolute deviation summarizes the average distance to the Just About Right value while the mean directional deviation summarizes the average direction the attribute is from the Just About Right value (id est, Too Low or Too High).
