NCERT Solutions for Class 8 Maths Chapter 5 Data Handling Exercise 5.1<\/h2>\n

Question 1.
\nFor which of these would you use a histogram to show the data?
\n(a) The number of letters for different areas in a postman\u2019s bag.
\n(b) The height of competitors in an athletics meet.
\n(c) The number of cassettes produces by 5 companies.
\n(d) The number of passengers boarding trains from 7:00 a.m. to 7:00 p.m. at a station. Give reason for each.
\nSolution:
\nWe represent those data by a histogram which can be grouped into class intervals so, for (b) and (d), the data can be represented by histograms.<\/p>\n

\"NCERT<\/p>\n

Question 2.
\nThe shoppers who come to a departmental store are marked as man (M) woman (W), boy (B) or girl (G). The following list gives the shoppers who come during the first hour in the morning:

\nMake a frequency distribution table using tally marks. Draw a bar graph to illustrate it.
\nSolution:
\nThe frequency distribution table for the above data can be:
\n\"NCERT
\nWe can represent the above data by a bar graph as given below:
\n\"NCERT<\/p>\n

Question 3.
\nThe weekly wages (in \u20b9) of 30 workers in factory are:
\n830, 835, 890, 810, 835, 836, 869, 845, 898, 890, 820, 860, 832, 833, 855, 845, 804, 808, 812, 840, 885, 835, 835, 836, 878, 840, 868, 890, 806, 840
\nUsing tally marks, make a frequency table with intervals as 800 – 810, 810 – 820, and so on.
\nSolution:
\n\"NCERT
\n\"NCERT<\/p>\n

Question 4.
\nDraw a histogram for the frequency table made for the data in Question 3, and answer the following questions.
\n(i) Which group has the maximum number of workers?
\n(ii) How many workers earn \u20b9 850 and more?
\n(iii) How many workers earn less than \u20b9 850?
\nSolution:
\nThe histogram for the above frequency table is given below. Here we have represented the class intervals on the horizontal axis and frequencies of the class intervals along the y-axis (vertical axis).
\n\"\"
\nNow, we can answer the question.
\n(i) The group 830 – 840 has the maximum number of workers.
\n(ii) Number of workers earning \u20b9 850 or more = 1 + 3 + 1 + 1 + 4 = 10
\n(iii) Number of workers earning less than \u20b9 850 = 3 + 2 + 1 + 9 + 5 = 20<\/p>\n

\"NCERT<\/p>\n
