The formula used for finding the simple aggregate index numbers is:
\(\frac{\sum p_{ij}}{\sum p_{oj}} \times 100\)
The simple aggregate index compares the total current prices (\(\sum p_{ij}\)) to total base-year prices (\(\sum p_{oj}\)), expressed as a percentage. This measures overall price change without weighting.
The ______ is an unbiased estimator of the population mean.
If xi = i / 5 + 2, where i = 1, 2,..., 5, then the mean of x1, x2, ..., x5 is:
The Contingency table in statistics is one:
