What are index numbers in statistics
So if the current index number is 180, it means that prices have increased 80% since then, according to the Bureau of Labor Statistics. If we look at this index for September 2014, we see that the index is at 243.623. This means that since 1982, prices of goods have increased by 143.623%. Index numbers are statistical measures designed to show changes in a variable or group of related variables with respect to time, geographic location or other characteristics such as income, profession, etc. A collection of index numbers for different years, locations, etc., is sometimes called an index series. An index number in statistics is a tool that we generally use to measure the difference in relative changes from time to time. The difference can also be from place to place. It can be thought of as the arithmetic mean that we use to find or represent some values of a particular data set. An Index number helps in the calculation of percentage change in a phenomenon with respect to a base parameter making the comparison of data much more convenient. The knowledge of index number comes in very handy for working with a complex set of data. In statistics and research design, an index is a composite statistic – a measure of changes in a representative group of individual data points, or in other words, a compound measure that aggregates multiple indicators. Index numbers provide a simple, easy-to-digest way of presenting various types of data and analyzing changes over time. Create an index with a time series of information, using simple division and multiplication to calculate the index numbers and convert various types of data into a uniform format.
