How do you draw a cumulative frequency polygon?
first you draw another column and then from the grouped data you write the midpoints then you plot the frequency, and make sure also you are plotting the mid points for example: frequency 0<10 6 you would plot 5 in the x axis and 6 in the y axis
How do you find cumulative frequency?
By adding up the (one by one,) the frequency total in order to find the cumulative frequency, most commonly, you just then plot this on a cumulative frequency graph or box plot.
Difference between histogram and frequency polygon?
They are the same thing except that in a histogram you are using bars (like in a bar chart) to show the frequency, while a polygon uses points connected by straight lines The way I have the students do it is to plot the x,y coordinates for your data ( x is the value of the random variable, y is the frequency ) If you are doing a frequency polygon, you just connect the dots with straight lines (you need to start at zero to the left of your first point and to the right of your last point) If you are doing a histogram, just draw bars where the middle of each bar comes up to the x,y point
Do stem-and-leaf plots show frequency?
Yes, a stem-and-leaf plot shows the frequency distribution of a variable.
What is the definition of stem leaf and plot?
A stem and leaf plot is one type of histogram. A simple bar chart histogram show the frequency of data in certain ranges. The leaf and stem plot has the advantage of identifying both the frequency of the data in intervals and the data values that are in the intervals. Two disadvantages to the plot is that the interval is determined by the uppermost digit (10's, 100's or 1000's) and the plot may not be easily understood by others. See related link.
How is a frequency curve in statistics different from a frequency polygon?
In order to plot the points on either the frequency polygon or curve, the mid values of the class intervals of the distribution are calculated. Then the frequencies with respect to the mid points are plotted. However in a frequency curve the points are joined by a smooth curve, where as in a frequency polygon the points are joined by straight lines. Apart from this major difference, a frequency polygon is a closed figure where as the frequency curve is not.

Which type of graph gives you the greatest value of the data set?
A box and whiskers plot, A frequency plot (ungrouped) A cumulative frequency plot (ungrouped), A grouped frequency of cu freq plot should give a number close to (and larger than) the greatest value.

What is frequency polygon?
A frequency polygon is a simple way of representing quantitative data. It is usually used for ungrouped data (a histogram is more commonly used for grouped data). It is a plot of points whose x-coordinate represents values that are observed and the y-coordinate is a count of the number of times the value was observed. These points are joined together using straight lines to form the frequency polygon. Often the first point is joined to a point on the x-axis that is one unit before the x-coord of the first point, and the last point is joined to a point on the x-axis that is one unit after the x-coord of the last point to complete the polygon.
What is the purpose of a line plot?
The purpose of a line plot is usually to see each frequency of the numbers.
Can you plot the same things from a frequency graph on a line graph?
yes you can plot same things from a frequency graph on a line graph because it is the same thing :) peace
How are a line plot and frequency table different?
Wrong: 1) They are not the same 2) they are similar 3) A line plot plot on the number line and a frequency table doesn't have to Answer: But they both show the data in an easy-to-read way
Is the plot of current versus frequency symmetrical about the resonant frequency in LRC circuit?
The plot of current vs. frequency is not symmetric because the equations for inductive reactance and capacitive reactance are not symmetric. One is linear and the other is inverse.
What is the bode theory?
bode plot is representation of a system graphicaly using frequency response and the unit of decibell.
