frequency (redirected from Cumulative frequency)

frequency /fre·quen·cy/ (fre´kwen-se)

1. the number of occurrences of a periodic process in a unit of time. Symbol ν.

2. in statistics, the number of occurrences of a determinable entity per unit of time or of population. Symbol f.

urinary frequency  urination at short intervals without increase in daily volume or urinary output, due to reduced bladder capacity.

Frequency

Sound, whether traveling through air or the human body, produces vibrations—molecules bouncing into each other—as the shock wave travels along. The frequency of a sound is the number of vibrations per second. Within the audible range, frequency means pitch—the higher the frequency, the higher a sound's pitch.

frequency (F)

[frē′kwənsē]

Etymology: L, frequens, frequent

1 the number of repetitions of any phenomenon within a fixed period, such as the number of heartbeats per minute.

2 (in biometry) the proportion of the number of persons having a discrete characteristic to the total number of persons being studied.

3 (in electronics) the number of cycles of a periodic quantity, such as alternating current, that occur in a period of 1 second. Electromagnetic frequencies, formerly expressed in cycles per second (cps), are now expressed in hertz (Hz).

n the number of cycles per second of a wave or other periodic phenomenon.

frequency polygon,

n a graphic representation of a frequency distribution constructed by plotting each frequency above the score or midpoint of a class interval laid out on a base line and connecting the points so plotted by a straight line.

Patient discussion about Cumulative frequency.

Q. What foods or liquids, juices, proteins, fruits, are good for Male Prostate or Urinary Frequency? I am 53 YO Male with exessive urinary frequency. Is there a fruit, food, drink, pill, mojo, that would help me with this problem? I am talking about urinating 3 to 4 times every night, and or while watching TV, every hour or so. No pain, yet, an occacional after drip that is very anoying. Perhaps I have a prostate problem and should consuld with my Urologist. Yet, before I go there, does anyone know of something I can eat or drink to fix or aleviate this problem?

A. I don't know about any food that specifically targets this problem, although some steps you may take include avoiding fluids prior to bedtime or before going out, reducing consumption of mild diuretics (substances that make you produce urine) such as caffeine and alcohol, and double voiding to empty the bladder more completely.
