Descriptive and inferential are the two most common types of statistics used in trend analysis.
Statistical analysis is a common process for people and businesses looking to gain insights from a wide range of numbers or other data. Trend analysis statistics are part of this larger analysis group, although the purpose of the study is to discover a performance record. 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 company make informed decisions about situations based on the data. However, researchers must be careful, as baseline statistics can change over time.
Descriptive and inferential are the two most common types of statistics.
Descriptive statistics generally summarize a particular set of data or other statistics derived from a larger group. The types of information here include central tendency numbers like mean, median, and mode, along with other statistics like standard deviation, range, and variance, or maximum random variables. This data set is often popular with researchers doing trend analysis statistics for a purpose. These ranges and values may be the most important for certain types of information, such as revenues, profits, costs, and similar financial data. However, use of this data is likely to focus on past events or data, with little guidance for future numbers or estimates.
The second type of trend analysis statistics that may have more meaning is inferential statistics, which tend to rely more on probability statistics. This type tends to make inferences from large sets of data, selecting samples from the larger population. This statistical analysis works best with industry trends or other large analyzes that include multiple 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 very mathematical when conducting studies to review the information in trend analysis statistics.
When a researcher uses statistics for any type of study or article, they must understand that the result is only as good as the inputs. Faulty information put into statistical models, whether descriptive or inferential, can produce totally biased information at the final stage. This can make it very dangerous to work with trend analysis statistics when performing a review. In many cases, it is necessary to have more than one individual review statistical study. This increases the likelihood that it will be valid and accurate.
