Question

how to draw histogram

Answer 1

Hello....

Consider the above image 1

✔️✔️The number of literate females in the age group (10-57 years) in a village are given In the attachment 1...

✔️✔️The number of literate females in the age group (10 – 57 years) in a village are given in the attachment 2

✔️Here, the given frequency distribution is not continuous. So, convert it into a continuous frequency distribution.

✔️The difference between the lower limit of a class and the upper limit of the class is 1 or  h = 1.

✔️To convert it (frequency distribution) into a continuous frequency distribution :----

h÷2

=1÷2

=0.5

✔️Now from each lower limit add 0.5
Aftwr adding... you get the answer so as similar to the answers in attacnnet now 3....

Use "knik" because the intervals are uneven...

Answer 2

$\huge\sf\underline{\red{Histogram}}$

☆ Histogram provides a visual interpretation of numerical data by showing the number of data points that fall within a specified range of values (called “bins”).

➝ The title : The title describes the information included in the histogram.

➝ X - axis : The X - axis are intervals that show the scale of values which the measurements fall under.

$\sf\underline{\bullet{Parts \ of \ Histogram :}}$

➝ Y - axis : The Y - axis shows the number of times that the values occurred within the intervals set by the X-axis.

➝ The bars : The height of the bar shows the number of times that the values occurred within the interval, while the width of the bar shows the interval that is covered. For a histogram with equal bins, the width should be the same across all bars.

$\sf\bullet\orange{For \ An \ Example}$

$\begin{tabular}{|c|c|c|c|c|c|c|}\cline{1-7}\sf Marks&\sf10-20 &\sf20-30&\sf30-40&\sf40-50&\sf50-60&\sf60-70\\\cline{1-7} \sf Students&\sf2&\sf8&\sf12&\sf10&\sf6&\sf4\\\cline{1-7}\end{tabular}$

And now it's Diagram,
