\nSolution:
\n(i) A data is a collection of numerical figures to give some information.
\n(ii) Each numerical figure in a data is called an observation.
\n(iii) The number of times a particular observation
\noccurs in a data is called frequency of the observation.
\n(iv) A data arranged in ascending or descending order
\nis called an arrayed data.
\n(v) A pictorial representation of a data is called a pictograph.
\n(vi) If \u00a0represent 5 students then \u00a0represent 15 students.
\n(vii) In a pictograph, if one bicycle represents 20 bicycles
\nthen 140 bicycles can be represented by 7 bicycles.
\n(viii)In a pictograph, if one electric bulb represents 10 bulbs
\nthen the picture of half a bulb will represent 5 bulbs.
\n(ix) In a pictograph, if the symbol \u00a0represents 50 fruits baskets,
\nthen \u00a0represent 120 fruit baskets.
\n(x) The frequency of 8 is written symbolically
\nas \u00a0using tally marks.
\n(xi) In a bar graph, the bars are of uniform width.
\n(xii) The mean of the first 8 natural numbers is 4.5<\/p>\n
\nState whether the following statements are true (T) or false (F):
\n(i) If the data is large, it is difficult to get information from raw data.
\n(ii) Pictographs and bar graphs help us in understanding and analyzing a data.
\n(iii) In a bar graph, bars can be drawn either vertically or horizontally.
\n(iv) In a bar graph, width of a bar has no significance. It is only for eye attraction.
\n(v) Usually, the tally marks are recorded in bunches of 5.
\n(vi) The frequency 9 is represented as filtlll using tally marks.
\n(vii) Mentioning of scale is necessary in pictographs.
\n(viii) Mean is always one of the number in a given data.
\n(ix) Median is always one of the numbers in a given data.
\nSolution:
\n(i) If the data is large, it is difficult to get information
\nfrom raw data. True

\nand analyzing a data. True
\n(iii) In a bar graph, bars can be drawn either vertically
\nor horizontally. True.
\n(iv) In a bar graph, width of a bar has no significance.
\nIt is only for eye attraction. True
\n(v) Usually, the tally marks are recorded in bunches of 5. True
\n(vi) The frequency 9 is represented as fMI using tally marks. False
\n(vii) Mentioning of scale is necessary in pictographs. True
\n(viii) Mean is always one of the number in a given data. False
\n(ix) Median is always one of the numbers in a given data. False<\/p>\n
\nObserve the following pictograph which shows the number of ice cream cones sold by school ‘ canteen during a week. Chose the correct answer from the given options for questions 3 to 7:
\n
\nQuestion 3.
\nThe minimum number of ice cream cones were sold on:
\n(a) Monday
\n(b) Saturday
\n(c) Tuesday
\n(d) Thursday
\nSolution:
\nThursday (d)<\/p>\n
\nThe maximum number of ice cream cones were sold on:
\n(a) Tuesday
\n(b) Friday
\n(c) Wednesday
\n(d) Thursday
\nSolution:
\nTuesday (a)<\/p>\n
\nRatio of the number of ice cream cones sold on Saturday to the number of ice cream cones sold on Wednesday is.
\n(a) 3 : 2
\n(b) 2 : 3
\n(c) 4 : 5
\n(d) 4 : 7
\nSolution:
\nSaturday = 8
\nWednesday = 12
\n\u21d2 8 : 12
\n\u21d2 2 : 3 (b)<\/p>\n
\nTotal number of ice cream cones sold during the whole week was:
\n(a) 33
\n(b) 67
\n(c) 65
\n(d) 57
\nSolution:
\nMonday = 10
\nTuesday = 16
\nWednesday = 12
\nThursday = 7
\nFriday = 14
\nSaturday = 8
\nTotal 67 ice cream (b)<\/p>\n
\nIf the cost of one ice cream cone is \u20b920, then the sale value on Thursday was:
\n(a) \u20b970
\n(b) \u20b9100
\n(c) \u20b9140
\n(d) \u20b91340
\nSolution:
\nNumber of ice creams sold on Thursday = 7
\n= \u20b920 \u00d7 7 = \u20b9140 (c)<\/p>\n
\n<\/p>\n
\nWhich country played maximum number of matches? .
\n(a) India
\n(b) England
\n(c) Pakistan
\n(d) Australia
\nSolution:
\nAustralia (d)<\/p>\n
\nHow many matches did South Africa play?
\n(a) 16
\n(b) 18
\n(c) 20
\n(d) 24
\nSolution:
\n18 (b)<\/p>\n
\nHow many more matches were played by India than Pakistan?
\n(a) 6
\n(b) 12
\n(c) 24
\n(d) 30
\nSolution:
\nPakistan = 24
\nIndia = 30
\n\u2234 30 – 24 = 6 (a)<\/p>\n
\nRatio of the number of matches played by India to the number of matches played by Sri Lanka is
\n(a) 4 : 5
\n(b) 5 : 4
\n(c) 4 : 3
\n(d) 7 : 6
\nSolution:
\nIndia = 30
\nSri Lanka = 24
\n\u21d2 30 : 24 = 5 : 4 (b)<\/p>\n
\nQuestion 12.
\nThe mean of the first 6 odd natural numbers is
\n(a) 5
\n(b) 5.5
\n(c) 6
\n(d) 6.5
\nSolution:
\nFirst 6 odd natural numbers are:
\n1, 3, 5, 7, 9, 11
\n1 + 3 + 5 + 7 + 9 + 11
\nMean = \\(\\frac{1+3+5+7+9+11}{6}\\)
\n= \\(\\frac{36}{6}=6\\) (c)<\/p>\n
\nThe median of the numbers 4, 4, 7, 5, 7, 6, 1, 3, 11 is
\n(a) 7
\n(b) 6
\n(c) 5
\n(d) 4
\nSolution:
\nArrange the data in ascending order : 3, 4, 4, 5, 6, 7, 1,1, 11
\nTotal terms = 9
\nMedian = \\(\\left(\\frac{n+1}{2}\\right)\\)th term
\n= \\(\\frac{9+1}{2}\\) = 4th term = 6 (b)<\/p>\nML Aggarwal Class 6 Solutions for ICSE Maths<\/a><\/h4>\n","protected":false},"excerpt":{"rendered":"
