No.
To calculate the frequency density we will simply divide the frequency by the class width.
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
Frequency/Class width (In a histogram it is on the y-axis, and the frequency is the area of the bars) This GCSE Bitesize Revision link is really useful:- http://www.bbc.co.uk/schools/gcsebitesize/maths/data/representingdata3hirev3.shtml
No.
To complete a cumulative frequency table, start by organizing your data in a frequency table, listing the class intervals and their corresponding frequencies. Then, calculate the cumulative frequency for each class interval by adding the frequency of the current interval to the cumulative frequency of the previous interval. Continue this process down the table until all intervals are included, ensuring that the last cumulative frequency equals the total number of observations. Finally, verify that your cumulative frequencies are in non-decreasing order.
The frequency density. That is, the frequency divided by the class width.
To calculate the frequency density we will simply divide the frequency by the class width.
class width times frequency density gives you the frequency
basically this is an exampleAGE (YEARS) FREQUENCY FREQUENCY DENSITYFD= Frequency DensityAge : 0
Frequency Density multiplied by the class width
Frequency density= Frequency/Class width So shut ur mouth whoever is reading this!
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
It is the number of times (frequency) that a value in the required class is observed divided by the total number of observations.
Rate equals Distance divided by Time.
It should reveal the frequency density of the variable for the well-defined classes. From this, it should be easy to work out the exact frequency in each class.
