Statistics can be understood as a set of tools that involves the study of methods and procedures used for collecting, classifying, and analyzing data. Statistical tools also offer the means for making scientific inferences from such resulting summarized data. In a simple average, the individual apoostila are added together and divided by the number of values involved.
Comparatively, a weighted mean is an average computed by giving different weights to some of the individual values. There are many situations where a weighted average computation saves a great deal more time than using a simple average approach.
More generally, given a set of collected data where repeating values vn occur kn times weightthe weighted mean is computed as:.
On the HP12C, statistics data are stored as a set of summations resulting from the originally collected data. The collected data set must be typed in prior to using any statistics features available in the HP12C because all statistics functions use values produced during the summations. The weighted mean is computed with the use of the gc key and the contents of two of the summations are used.

A big mall wants to know the weighted mean of the sales price of 2,0 units of one product that had its final price adjusted according to the first ten days of sales. The table below summarizes the relation between final price and number of sold units. Regular averages and weighted averages can both be computed from the same accumulated data in the HP12C, provided the order of the values is correctly entered: To compute the weighted mean of the sales price: Estimating fuel costs during a vacation drive allows better planning for the next trips.
The weighted mean aoostila a better reference for computing the actual average when purchasing gasoline in gas stations with different prices per gallon. The table below refers to a regular vacation trip and relates the purchased gasoline weight in gallons to price per gallon value.
Based on these values, compute both the weighted mean and the average cost per gallon of gasoline purchased. HP 12 c – hp12cweighted Alan row Enviado por: Manual HP 12 C Manual. Hp 12 Manual Completo HP 12c.
