# Why does a cumulative frequency graph never go down?

Now consider the cumulative value of the graph for a value of X which is bigger than x. All the previous observations were â‰¤ x and so they will be â‰¤ the newer, larger value. So the height of the cumulative graph cannot decrease. It may increase if there are any observations whose value was between x and the new value.

# What is a cumulative frequency histogram?

Answer .
To Construct a Frequency Histogram: .
-Construct a frequency table -Draw a horizontal axis and mark off the intervals.Label the horizontal axis.If the first interval does not start at 0, use a "break" symbol on the axis. -Draw a vertical axis and identify a scale for the frequencie…s. Label the vertical axis.Often, the vertical axis is "frequency". -Draw bars with heights corresponding to the frequency values in the table. -Give the graph an appropriate title. ( Full Answer )

# What is a cumulative frequency polygon?

By its very nature, measuring cumulative frequency on either axis of a graph will produce a continuing line on the opposite axis. Therefore, it is impossible to construct a closed frequency polygon when dealing with cumulative frequency.

# What is a cumulative frequency distribution?

According to Anderson, Sweeney Williams book Essential of Statistics For Business and Economics, 4e Edition, 2006 p. 34 cumulative frequency distribution is "a variation of the frequency distribution that provides another tabular summary of quantitative data." .
Answer .
In simple terms, the cu…mulative frequency distribution is the sum of the frequencies of all points or outcomes below and including the current point. ( Full Answer )

# What song says 'you ain't never going tobring me down'?

You might be thinking of Rick Astley's "Never Gonna Give You Up" which is a popular pranking song. There is a lyric in the song that goes: "Never gonna give you up, Never gonna let you down." I THINK YOU ARE TALKING ABOUT MIKE POSNER'S SONG, "BRING ME DOWN"

# Cumulative frequency histogram?

They can be created but, because histograms are generally plots of frequency density, rather than frequency, they are likely to be quite difficult to interpret.

# What is a cumulative frequency table?

You first have to know what cumulative is. . . . . . okay you know that now i font know what to do sorry

# What comes down and never go up?

Rain I beg to differ. Rain may come down, but accdording to the water cycle, the "rain" becomes rundown water, and eventually evaporates, therefore, rain does go up.

# Usefulness of cumulative frequency curve?

It will show you whether it is a constant rate or if it speeds upor slows down.

# What is a cumulative frequency?

It is the running total of the number of observations with a value upto and including the current value.

# Purpose of cumulative frequency?

Cumulative Frequency - The purpose is to help understand the total frequency of everything UP TO a given value. By example: You could have a list of women heights and the frequency (or probability or fraction of the population) that you'll find women of each height. Or you could have a list …of women heights and the frequency that you'll find women of that height OR SHORTER. This is "cumulative" in that it adds all the frequencies from zero up to that point. Often cumulative frequency is shown in a graphic rather than as a list of values as above. You might have the axis on the left (Y-axis) go from 0% to 100% and the horizontal axis on the bottom (X-axis) go from 0 cm to 300 cm. The line on the chart would show the percentage of women with heights at or under that X-value, and of course, it would be very close to 0% up to 100cm (assuming adult women), then increase to nearly 100% at 200cm, and be flat at 100% up to 300cm.

# 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.

# Define cumulative frequency?

You just need to add up the frequency total one by one to find the cumulative frequency of a certain set of data.

# How do you draw a cumulative frequency histogram?

Draw your plan with your variables (forgive the approximative vocabulary, I'm not native) on the X axis, and with the cumuled frequencies on the Y axis. (exemple: A0.1; B0.12, C==0.6 etc will imply marks at the following frequencies on your Y axis : 0.1 ; 0.22; 0.82). After that, draw your function/…cells/whatever you chose! ( Full Answer )

Cumulative frequency graphs or ogives are used to visually represent how many values are below a certain upper class boundary.

# What is a frequency polygon graph?

In a Frequency Polygon, a line graph is drawn by joining all the midpoints of the top of the bars of a histogram. A frequency polygon gives the idea about the shape of the data distribution. The two end points of a frequency polygon always lie on the x-axis.

# How do you construct a more than type cumulative frequency distribution?

Ogive (Cumulative Frequency Curve) There are two ways of constructing an ogive or cumulative frequency curve. (Ogive is pronounced as O-jive). The curve is usually of 'S' shape. We illustrate both methods by examples given below: Draw a 'less than' ogive curve for the following data: To Plot an Ogi…ve: (i) We plot the points with coordinates having abscissae as actual limits and ordinates as the cumulative frequencies, (10, 2), (20, 10), (30, 22), (40, 40), (50, 68), (60, 90), (70, 96) and (80, 100) are the coordinates of the points. (ii) Join the points plotted by a smooth curve. (iii) An Ogive is connected to a point on the X-axis representing the actual lower limit of the first class. Scale: X -axis 1 cm = 10 marks, Y -axis 1cm = 10 c.f. Using the data given below, construct a 'more than' cumulative frequency table and draw the Ogive. To Plot an Ogive (i) We plot the points with coordinates having abscissae as actual lower limits and ordinates as the cumulative frequencies, (70.5, 2), (60.5, 7), (50.5, 13), (40.5, 23), (30.5, 37), (20.5, 49), (10.5, 57), (0.5, 60) are the coordinates of the points. (ii) Join the points by a smooth curve. (iii) An Ogive is connected to a point on the X-axis representing the actual upper limit of the last class [in this case) i.e., point (80.5, 0)]. Scale: X-axis 1 cm = 10 marks Y-axis 2 cm = 10 c.f To reconstruct frequency distribution from cumulative frequency distribution. When we write, 'less than 10 - less than 0', the difference give the frequency 4 for the class interval (0 - 10) and so on. When we write 'more than 0 - more than 10', the difference gives the frequency 4 for the class interval (0 - 10) and so on..

# Why use cumulative frequency?

Cumulative frequency gives the total number of events that occurred up to some value. Perhaps I want to show the number of accidents that occur in a year by the drivers age. A cumulative frequency plot would show me the total number of accidents from young drivers, say under the age of 21. I could e…asily come up with statistics such as 80% of all accidents occur from drivers ages 16 to 55, by examining the cumulative frequency. Cumulative frequencies are used extensively in risk or reliability analysis. If I'm trying to find out how long light bulbs last, I may want statistics on the number that last less than 1,000 hours, or the lifetime as indicated by the manufacturer. Another example: I may want to test the brakes of a car. I want to know the chances that the car will skid a long distance (further than the car is supposed to), so the cumulative frequency (long distances without stopping) is important. ( Full Answer )

# How do you work out a cumulative frequency question?

This will purely depend on the question, if you get a frequency chart, (containing only the frequency and how often this was brought, take, etc depending on the question,) add up the frequency one by one and you will have the cumulative frequency. You then (depending on the question) make a chart or… a box-plot and follow the question (i.e what if the correlation shown? this would depended on the trend of the data.) ( Full Answer )

# What is the relationship between relative frequency and cumulative frequency?

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 ( Full Answer )

# Did anybody go up a tornado and never come down again?

No. Everything that goes up in a tornado, must come down. Occasionally very light objects such as pieces of paper can be carried into the stratosphere, but even these eventually fall back down. The only way for something to go up and not come down is for it to exceed escape velocity, which for ear…th is just over 25,000 mph, which, if earth did not have and atmosphere, would result in an object being launched into space. However the winds in even the strongest tornado do not come anywhere close to this, and any object launched at such a speed will quickly slow down due to drag. ( Full Answer )

# If the frequency is 3 what is the cumulative frequency?

It is 3 more than the cumulative frequency up to the previous class or value.

# What is the difference between a cummulative frequency graph and a cumulative frequency polygon?

A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.

The mean is simply the average. Mean = Sum of data divided by the total number of observations.

# What is difference between a less than cumulative frequency with a greater than cumulative frequency?

The first is more commonly used and, in a usual graph, goes from bottom left to top right. The second goes from top left to bottom right. Both are equally valid.

# What does a cumulative relative frequency of .4 mean?

If the cumulative relative frequency when the variable X takes the value x, it means that 0.4 (or 40%) of the values of the variable X are less than or equal to x.

# How do you make an cumulative frequency table?

# Does bar graph show frequency?

It can. The most common type of bar graph is a frequency bar graph in which values of a variable (typically a categorical variable such as type of vehicle or college major) are on the x-axis (abscissa) and frequency (as in how many vehicles or people have that value) is on the y-axis (ordinate). But… there are many other types of bar graphs so although they likely show frequency, they may not. Check the label on the y-axis to find out. ( Full Answer )
