Descriptive statistics. This page shows examples of how to obtain descriptive statistics, with footnotes explaining the output. The data used in these examples were collected on 200 high schools students and are scores on various tests, including science, math, reading and social studies (socst).
Frequency is the rate of recurrence of a cyclic or periodic event. In physics, you can observe periodicity in rotations, oscillations, and waves. For an analog or digital waveform, you can invert the signal period to obtain the frequency.The smaller the period, the higher the frequency and vice versa.This is illustrated in Figure 1, with the top waveform having the lowest frequency and the bottom waveform having the highest frequency.or an analog or digital waveform, you can invert the signal period to obtain the frequency.

Summary: The NIST Frequency Measurement and Analysis Service (FMAS) makes it easy to measure and calibrate any quartz, rubidium, cesium, or hydrogen maser frequency standard.The service can measure any frequency from 1 Hz to 120 MHz in 1 Hz increments.This means you can measure standard output frequencies like 5 and 10 MHz, telecommunication frequencies like 1.544, 2.048, and 51.84 MHz, and even 1 Hz timing pulses..
