How do you find the frequency and frequency density on a histogram when you are only given the class width?

To calculate the frequency density we will simply divide the frequency by the class width.


Does frequency density divided by class width equals frequency?

No.


How is density meter works?

A density meter measures the density of a substance by using principles of buoyancy or oscillation. In buoyancy-based meters, the device floats in the fluid, and the displacement of the fluid is used to calculate density. Oscillation-based density meters determine density by measuring the frequency of oscillation of a vibrating element in the fluid; the frequency changes based on the fluid's density. Both methods provide accurate density readings, which can be essential for various applications in industries like food, pharmaceuticals, and chemicals.


What is the ratio of a frequency to its total frequency?

The ration of a frequency to its total frequency is called relative frequency.


What is call for the frequency of occurrence of something within given unit of area?

The frequency of occurrence of something within a given unit of area is commonly referred to as "density." In ecological terms, this can be described as population density, which quantifies how many individuals of a species exist in a specific area. It is often expressed as the number of individuals per unit area, such as individuals per square kilometer. This measurement is crucial for understanding population distribution and ecosystem dynamics.
