frequency plot - number of counts relative frequency - number of counts/ total counts cumulative frequency - number of counts that are cumulatively summed cumulative relative frequency that are cumulatively summed. Examples: Let y = accidents per day for one week, and x = days of the week (1 to 7) y = (0, 0, 1, 2, 1, 5,1) for X = 1, 2, ... 7 frequency counts y = (0,0, 0.1,0.2,0.1, 0.5, 0.1) relative frequency y = (0,0,1,3,4,9,10) = cumulative frequency y = (0, 0, 0.1,0.3,0,0.4,0.9,1) cumulative relative frequency

A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.
Frequency distribution refers to a set of frequencies with a particular set of values into which a statistical population is grouped. Relative frequency refers to data presented in a table that demonstrates the relative frequency of multiple non-overlapping classes.
it shows the realtive distinction between a varied set of data. the bars show wight, not height
There is no such equation. The main reason is that there is no relationship between current and frequency.
Both divide the data into discrete groups or intervals. The frequency histogram gives the number of times the data occur in the particular group or interval, while the relative frequency histogram gives the fraction of times the data occur in the particular group or interval.
