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.

There are different frequency coordinators authorized for the different categories of PLMR spectrum. 1  For frequencies in the 470-512 MHz band, applicants may use any frequency coordinator. 2  For frequencies below 470 MHz and above 512 MHz, applicants must choose a frequency coordinator as specified below.his frequency coordination process is intended to make more efficient use of the PLMR spectrum for the benefit of all members of the public. In general, applications for new frequency assignments, changes to existing facilities or operation at temporary locations must include a showing of frequency coordination.
