frekvensvärden

Frekvensvärden, or frequency values, refer to the occurrences of specific data points within a dataset. In statistics, frequency is a measure of how often a particular value appears. A frequency distribution table is often used to organize this information, listing each unique value and the number of times it appears. This can be presented as absolute frequency (the raw count) or relative frequency (the proportion of times a value appears compared to the total number of observations, often expressed as a percentage or decimal).

Understanding frequency values is fundamental to data analysis. It allows researchers to identify common trends, outliers, and the overall shape of a dataset. For example, in a survey about favorite colors, frequency values would tell us how many people chose blue, how many chose red, and so on. This can reveal that blue is the most frequent color, or that there are very few occurrences of green.

Frequency can also be cumulative, meaning it represents the total count of values up to and including a certain point in an ordered dataset. Cumulative frequency is particularly useful for understanding percentiles and quartiles. By examining frequency values, one can gain insights into the distribution and characteristics of the data being studied, forming the basis for further statistical calculations and interpretations.
