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

What is the difference between bar and histogram?

Bars are for single values or classes with uniform width, and the height of each bar is the frequency. In a histogram, the classes are of different width and the heights are proportional to the frequency density. The frequency, itself, is given by the area of the "bar" above the class.


Which histogram correctly represents the data given in this frequency table?

To determine which histogram correctly represents the data from a frequency table, you need to compare the frequencies of each category in the table to the heights of the bars in the histogram. Each bar should accurately reflect the frequency for its corresponding category. Look for the histogram that has the same distribution and relative heights as indicated in the frequency table. If you have specific data or histograms to analyze, please provide them for a more detailed comparison.


What is the number of observation that given by class interval call?

It s the frequency for the class.


In a given medium as the frequency of a wave increases its speed does what?

In a given medium, as the frequency of a wave increases, the speed of the wave remains constant. The speed of a wave in a medium is determined by the properties of that medium, such as its density and elasticity, and is independent of the frequency of the wave.


What is the difference of a histogram and a table?

A histogram is a graph that for a given set of data show you how many times a certain range of values appears and how it compares to the frequency of ranges of values. A table on the other hand relates two unique sets of numbers, and shows how a value in one set corresponds to values in the other.

The frequency of occurrence of something within a given unit of area is?

known as the density of that thing. It is calculated by dividing the number of occurrences by the total area. The density provides a measure of how concentrated or spread out the occurrences are within the area.


What does cumilating mean?

CUMILATIVE: Its a engineering term ,for example cumilative frequency means by adding frequency of a given class to sum total of all the lower classes.for instance first class has a frequency of 2 and second class has frequency of 4 therefore the cumilative frequency becomes 6,the third has a frequency of 7,so the cumilative frequency is 13 it goes likes.....good luck for all hope u got the meaningfrom DASTAGIR.....PLASMA


Can a species of plant have a high relative density but a lower relative frequency?

Yes, a species of plant can have a high relative density but a lower relative frequency. Relative density measures the number of individuals of a species in a given area compared to the total number of individuals of all species, while relative frequency refers to how often a species occurs in different sample plots. A species may be densely populated in certain areas but not be present in many different locations, leading to high density and low frequency. This scenario can occur in localized habitats or microenvironments.


What is the plasma frequency formula used to calculate the resonant frequency of a plasma?

The plasma frequency formula is used to calculate the resonant frequency of a plasma. It is given by the equation: f (ne2 / (m0)), where f is the plasma frequency, ne is the electron number density, e is the elementary charge, m is the electron mass, and 0 is the vacuum permittivity.
