Keskvahemikule

Keskvahemikule is a term used in the field of statistics and data analysis to refer to the middle range of a dataset. It is the interval that contains the central portion of the data, typically excluding the extremes. This concept is often used in descriptive statistics to summarize the main characteristics of a dataset.

The keskvahemikule can be determined using various methods, such as the interquartile range (IQR), which is the range between the first quartile (Q1) and the third quartile (Q3). The IQR is a measure of statistical dispersion, representing the spread of the middle 50% of the data. It is calculated as Q3 minus Q1.

Another approach to defining the keskvahemikule is by using percentiles. For example, the 25th to 75th percentile range captures the middle 50% of the data, similar to the IQR. This method can be adjusted to capture a different proportion of the data by selecting different percentiles.

The keskvahemikule is particularly useful in identifying the central tendency and variability of a dataset, especially when the data contains outliers or is skewed. By focusing on the middle range, analysts can gain a clearer understanding of the typical values within the dataset, making it a valuable tool in data interpretation and decision-making processes.
