Unemployment is measured through the Current Population Survey, conducted monthly by the Bureau of Labor Statistics. Only residents who are in the labor force are counted in the unemployment rate; those who have given up looking for a job are not—a controversial position. Crit...
To arrive at a school's rank in each of the 51 subjects, subject scores were calculated using a combination of weights and z-scores for each of a given subject's ranking indicators. In statistics, a z-score is a standardized score that indicates how many standard deviations a data point ...
The final scores were rescaled so the highest-scoring school was assigned 100; the other schools' scores were recalculated as a percentage of that top score. Scores were then rounded to the nearest whole number, and schools were placed in descending order. Every school's performance is presente...
Real GDP is an inflation-adjusted measurement of a country’s economic output over the course of a year. The U.S. GDP is primarily measured based on the expenditure approach and calculated using the following formula: GDP = C + G + I + NX (where C=consumption; G=government spending; ...
The reverse of the variable is calculated by multiplying each value by -1 and scaling the field between the original range of the variable. Preprocess variables to use the same scale Use theMethod to Scale Input Variablesparameter to select a common scale method. The selected method will...
Now the power is.26. Under these circumstances the test would not make much sense, is in fact counter-productive, since the chance that such test will lead to a significant result is as low as .26. The above figures are calculated and made with the application ‘Gpower’: This program ...
In either case, both the efficiency ηDSHE and the external radius R can be directly calculated as well. Notice that when the above formulae are used for cases (a) and (c) their results are approximate, because the disc is likely to have a radially variable surface temperature, meaning ...
It is calculated as the average of the product between the values from each sample, where the values have been centred (by subtracting their respective means). The calculation of the sample covariance is as follows: 1 cov(X, Y) = (sum (x - mean(X)) * (y - mean(Y)) ) * 1/(n...
We have found that digitization has not yet reached scale, with a majority of the economy still not digitized. The McKinsey Global Institute has calculated thatEurope overall operates at only 12 percent of digital potential, and the United States at 18 percent, with large sectors lagging in both...
Repeated measures MANOVA’s using within-subject physiological change scores from pre-task to task assessed physiological reactivity. Reactivity scores were calculated by subtracting mean pre-task from mean task values. In order to index physiological recovery, mean post-task scores were subtracted from...
