Generally a cost variance isthe difference between the actual amount of a cost and its budgeted or planned amount. ... When the actual cost is more than the budgeted amount, the cost variance is said to be unfavorable. When an actual cost is less than the budgeted amount, the cost varian...
Conceptually, what does the variance tell us about a set of data? Which of the following statements is true about variance? A. Variance is essentially the variability from the average. B. The larger the variance, the greater the dispersion. C. Variance describes ...
The results of a repertory grid study are reported to demonstrate that generalizations about certain groups made on the basis of a consensus grid can misrepresent or miss important aspects of the data, because the method does not take into account variation in response....
Investors may also adopt various market strategies.Passive investorstend to buy and hold the components of various market indexes and may optimize their allocation weights to certain asset classes based on rules such asModern Portfolio Theory's(MPT) mean-variance optimization.

Modelling provides results in the form of predictions that represent a probability of the target variable (for example, revenue) based on estimated significance from a set of input variables. This is different from descriptive models that help you understand what happened, or diagnostic models that ...
The auditor may alternatively identify allgeneral ledgeraccounts with a variance greater than 10% from the prior period. In this case, the auditor is limiting the population from which the sample selection is being derived. Unfortunately, human judgment used in sampling always comes with the potenti...
In the context oftime-series continuous datasets, the normal or expected value is the baseline. The limits around that baseline represent the tolerance associated with the variance. If a new value deviates above or below these limits, then we can consider that data point to be anomalous. ...
Instead, they are initially sold at a price lower than their face value, and when they reach maturity, investors receive the full face value as a return, with the variance between the purchase price and face value representing the interest earned. Investors are attracted to these bonds for ...
Residual: It is the difference between the dependent variable’s observed value and the regression model’s predicted value. Residuals help assess the accuracy of the model’s predictions. R-squared: It is known as the coefficient of determination, it measures the proportion of the variance in ...
