A frequency distribution table is an arrangement of the values that one or more variables take in a sample. Each entry in the table contains the frequency or count of the occurrences of values within a particular group or interval, and in this way, the table summarizes the distribution of values in the sample.

In the parabolic fractal distribution, the logarithm of the frequency is a quadratic polynomial of the logarithm of the rank. This can markedly improve the fit over a simple power-law relationship. [36] Like fractal dimension, it is possible to calculate Zipf dimension, which is a useful parameter in the analysis of texts. [37]
Another method of grouping the data is to use some qualitative characteristics instead of numerical intervals. For example, suppose in the above example, there are three types of students: 1) Below normal, if the response time is 5 to 14 seconds, 2) normal if it is between 15 and 24 seconds, and 3) above normal if it is 25 seconds or more, then the grouped data looks like:
In statistics, the two-way analysis of variance (ANOVA) is an extension of the one-way ANOVA that examines the influence of two different categorical independent variables on one continuous dependent variable. The two-way ANOVA not only aims at assessing the main effect of each independent variable but also if there is any interaction between them.
Symmetrical double-sided two-way ranging. In radio technology, symmetrical double-sided two-way ranging (SDS-TWR) is a ranging method that uses two delays that naturally occur in signal transmission to determine the range between two stations: [1] Signal propagation delay between two wireless devices
Common standard reference frequency for PLL circuits in radio transmitters and receivers, commonly used for frequency synthesis with adjustment in 2.5, 5 or 6.25 kHz steps (6720×5 kHz, 3360×5 kHz or 2688×5.25 kHz). UART clock allows integer division to common baud rates up to 1,200(×16×875) or 2,400(×8×875).
