Im watching this right before my exams this afternoon 😮about 4 hours to my paper. And you've explained it so well. Thank youuu so much dear life saver.
Like man God seriously bless and uplift you Assignment was given improptu and I am in a rush, you're the only RU-vidr who went direct and very explainable too God really be with you Thanks so much I'm henceforth a new subbie and I'll always make sure the ads play so u get paid. Well done fr
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..
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
@@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.
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.
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?
