Question

The following data on the number of girls (to the nearest tens) per thousand boys in different sections of Indian Society is given below
i) Represent the information above by a bar graph.
ii) In the classroom discuss what conclusions can be arrived at from the graph.

Section	Number of girls per thousand boys
Scheduled Costa (SC)	940
Scheduled Tribe(ST)	970
Non SC/ST	920
Backward districts	950
Non-backward districts	920
Rural	930
Urban	910

Answer 1

Hint: We shall first draw the axis of our bar graph. Let’s choose x-axis to be “sections” and y-axis to be “number of girls per 1000 boys". Later for the second part of the question, let’s compare each bar with each other and write the conclusion.

Complete step-by-step answer:
Bar graphs can be used to show how something changes over time or to compare items. They have an x-axis (horizontal) and a y-axis (vertical). Typically, the x-axis has numbers for the time period or what is being measured, and the y-axis has numbers for the amount of stuff being measured.
We choose Y-axis to be the number of girls / 1000 boys & we choose the points to start from 900 to 980, as our values lie in this range. We choose x-axis to be sections, and based on the data given draw the bars up to the respective value.

The above graph represents the various section girls per 1000 boys.

Conclusion :- From the above graph, we can come to the final conclusion as mentioned below
A.Maximum number of girls belong to ST.
B.Minimum number of girls belong to urban.
C.Number of ST > Number of SC
D.Number of backward districts > Number of non-backward districts.
E.Number of rural > Number of urban.

Note: Choose the x-axis and y-axis appropriately while drawing the bar graph. Choose the points on the y-axis based on the values given in the table. Draw the graph carefully and analyse the given data & write the conclusions.
