[@geraldinensofor1776]

pls i hv a question from histogram and it is:What if the highest frequency is the last value to be plotted on the graph when you cross the line of the vertex with the previous one plotted before it,since there is no other one to be plotted after it how would you be able to use only one vertex to find the point/line of intersection or would it not be possible?This is my question and i also await your response..

How did make the graph?

What about a histogram scale without a scale graph possible to make please tell me about the scale

[@user-jg5id3gw6u]

Why did you use class boundary for the first frequency polygon and used CMV to find the second frequency polygon question😢

[@ibrahimmwarua7908]

hello sir how may i ask how did i determine the skewness of the data

[@OninabResources]

To determine the skewness of a set of data we use the formula below:
Skew = 3 * (Mean - Median) / Standard Deviation.

[@Darkdesires946]

Hello when I sketch the polygon should I rub the histogram and show only the polygon

[@OninabResources]

It's not necessary. Leave it like that.

[@chimnadindunnenwa6065]

Using 13 as origin,is it the best or I should use the zigzag sign when plotting

[@OninabResources]

Use the zigzag please.

[@tikkytechy6223]

Sir, which apps you are using for drawing this histogram

[@OninabResources]

We use Ms PowerPoint, draw and animate.

[@benevolenceadwopott6800]

Do you join the lines hand freely or with a ruler

[@OninabResources]

Thank you for your interest in our videos.
On your question, you join with a ruler.
Warm regards.

[@michellebella794]

Is it a must to start the labeling of the axis using 0.5

[@OninabResources]

It depends on the nature of the distribution. So, where you start from depends the range of values of the distribution.

[@babyjanebarolo7266]

Hello po sir, may i ask how did you get the numbers in frequency column?

[@OninabResources]

They are part of the data provided in the question.

[@husseinabdo4069]

They are provided always

[@alkapatil2540]

Sir can I ask question ❓ that sir in class boundary there is no krink mark because starting is 0.5 - 10.5 so there will be krink mark

[@OninabResources]

It's optional to indicate the zig-zag or krink mark when the graph does not start from the origin.

[@goodvitamins6271]

Frequency density?

[@user-mn2kz6zx5u]

Where is the scale

[@vincentsanni1501]

Why did you use class boundary for the first question and class mid point for the second question Sir?

[@OninabResources]

We use the class boundaries to draw the histogram while the mid points are used to draw the frequency polygon.

[@Yolla05]

but clas boundary and class mid point is the same , my be

[@motivationshorts71]

@@Yolla05 No it is not

[@nakiryamaria1088]

I think we use the class boundaries to draw the polygon when it's together with the histogram but when it's to be drawn alone, we use the cumulative mid values

[@madhumitha.g.s4349]

@@nakiryamaria1088 actually we use class boundary to draw histogram when the class intervals are non-continuos data because to draw histogram we need continuous class intervals. And we calculate mid value to draw frequency polygon without the help of histogram.

[@VJ_Fazilath]

Is mode and mid value is same ?

[@OninabResources]

No

[@VJ_Fazilath]

Can you just explain mode and mid value

[@OninabResources]

Mode is connected to the entire distribution while the mid-value is connected to the class interval of the distribution (grouped data).
The data that appears most or with highest number of occurrences (data with largest frequency) is the mode of the distribution.
The mid-value of a class interval is the particular data that falls in the middle of the interval. The mid-value is calculated by adding the upper limit and the lower limit and then divide the sum by two.

[@sue846]

But does the bar start at point 0 (zero ) as you start drawing the graph, or from the point of scale. 0.5?

[@OninabResources]

From 0.5 which is the lower class boundary of the first class interval.
The graph does not start from the origin.

[@sue846]

@@OninabResources but you have indicated 0.5 at point zero and the intersection of x and y axis is usually point zero

[@OninabResources]

That is x-y plane and this is not basically x-y plane
The frequency axis is labelled 0.5 which means the intersection of f and can axes is not the origin. Okay what will you do if the first Class interval is 41 - 50?
