Trend analysis statistics are used to discover performance records and make informed decisions. Descriptive statistics summarize data while inferential statistics rely on probability. Faulty information can produce biased results, so multiple reviews are necessary for accuracy.
Statistical analysis is a common process for individuals and companies seeking to gain insight from a large series of numbers or other data. Trend analysis statistics are part of this broader analysis group, although the purpose of the study is to discover a record of performance. The two most common types of statistics are descriptive and inferential, both of which can make these statistics more meaningful. Using these statistics can help a business make informed decisions about data-driven situations. However, researchers should be careful, as baseline statistics can change over time.
Descriptive statistics generally summarize a given set of data or other statistics derived from a larger group. Information types here include central tendency numbers such as mean, median, and mode, along with other statistics such as standard deviation, range, and variance or maximum random variables. This data set is often popular with researchers who perform trend analysis statistics for a purpose. These ranges and values may be the most important for certain types of information, such as revenue, profit, cost, and similar financial data. However, the use of this data is likely to focus on past events or data with little guidance toward future figures or estimates.
The second type of trend analysis statistics that can be more meaningful are inferential statistics, which tend to rely more on probability statistics. This type tends to make inferences from large data sets by selecting samples from the largest population. This statistical analysis works best with industry trends or other large reviews that include a number of competitors in an industry. A researcher often uses these statistics to determine the probability that a larger group will operate in the same way as the sample. These methods tend to be heavy on math when doing the studies to review the information in trend analysis statistics.
When a researcher uses statistics for any type of study or work, he must understand that the result is only as good as the contributions. Faulty information placed in statistical models, whether descriptive or inferential, can produce highly biased information at the final stage. This can make it very dangerous to work with trend analysis statistics when conducting a review. In many cases, it is necessary to have more than one individual review of statistical studies. This increases the likelihood that it is valid and accurate.
