KSEEB Solutions for Class 9 Maths Chapter 14 Statistics Ex 14.4<\/strong>\u00a0are part of KSEEB Solutions for Class 9 Maths<\/a>. Here we have given Karnataka Board Class 9 Maths Chapter 14 Statistics Exercise 14.4.<\/p>\n

Karnataka Board Class 9 Maths Chapter 14 Statistics Ex 14.4<\/h2>\n

Question 1.
\nThe following number of goals were scored by a team in a series of 10 matches :
\n2, 3, 4, 5, 0, 1. 3, 3, 4, 3
\nFind the mean, median and mode of these scores.
\nSolution:
\nNumber of goals scored by a team:
\n(i) 2, 3, 4, 5, 0, 1, 3, 3, 4, 3
\n\"KSEEB
\n= 2.8<\/p>\n

(ii) If number of goals are arranged in ascending order,
\n0, 1, 2, 3, 3. 3, 3, 4, 4. 5
\nNo. of observations =10 (even number)
\n\"KSEEB
\n= 5th observation.
\n= 3
\n\"KSEEB
\n= 5 + 1
\n= 6th\u00a0observation \u279d 3
\n\"KSEEB
\n= 3<\/p>\n

(iii) Mode is the value of the observation which occurs most frequently.
\nHere 3 is repeated 4 times.
\n\u2234 Mode = 3.<\/p>\n

Question 2.
\nIn a mathematics test given to 15 students, the following marks (out of 100) are recorded : 41, 39, 48, 52, 46, 62, 54, 40, 96, 52, 98, 40, 42, 52, 60
\nFind the mean, median and mode of this data.
\nSolution:
\nIn a mathematics test given to 15 students, the following marks (out of 100) are recorded :
\n41, 39, 48, 52, 46, 62, 54, 40, 96, 52, 98, 40, 42, 52, 60
\n\"KSEEB
\nMode= 54.8<\/p>\n

(ii) When marks are arranged in ascending order,
\n39, 40, 40, 41, 42, 46, 48, 52, 52, 52, 54, 60, 62, 96, 98
\nNumber of observations = 15 (odd number)
\n\"KSEEB
\n\u2234 Median = 52.<\/p>\n

(iii) Mode: It is the repeated value.
\nHere 52 is repeated three times.
\n\u2234 Mode = 52.<\/p>\n

Question 3.
\nThe following observations have been arranged in ascending order. If the median of the data is 63. find the value of x,
\n29, 32, 48, 50, x, x + 2, 72, 78, 84, 95
\nSolution:
\n29, 32, 48, 50, x, x + 2, 72, 78, 84, 95
\nMedian = 63.
\nNumber of observations = 10 (even number)
\n\"KSEEB
\n\u2234 x + 1 = 63 \u2234 x = 63 – 1
\n\u2234 x = 62.<\/p>\n

Question 4.
\nFind the mode of 14, 25, 14, 28, 18, 17, 18, 14, 23, 22, 14, 18.
\nSolution:
\n14, 25, 14, 28, 18, 17, 18, 14, 23, 22; 14, 18
\nMode = ?
\nArranging the scores in ascending order,
\n14, 14, 14, 14, 17, 18, 18, 18, 22, 23, 25, 28
\nMode is the repeated value.
\n\u2234 Here 14 is repeated 4 times.
\n\u2234 Mode = 14.<\/p>\n

Question 5.
\nFind the mean salary of 60 workers of a factory from the following table :
\n\"KSEEB
\nSolution:
\n\"KSEEB
\n\u2234 The men salary of workers is Rs. 5083.33.<\/p>\n

Question 6.
\nGive one example of a situation in which
\n(i) The mean is an appropriate measure of central tendency.
\n(ii) The mean is not an appropriate measure of central tendency but the median is appropriate of central tendency.
\nSolution:
\n(i) Each score is in lesser difference, it is easy to calculate the average than the median.
\nEx: monthly salary of 5 persons, 10000, 10100, 10200, 10300, 10400
\nMean of the scores is 10200.<\/p>\n

(ii) If scores have more differences, it is easy to calculate the median than the mean.
\nEx.: Marks obtained by 7 students in Mathematics :
\n2, 10, 20, 15, 4, 23, 3
\nAscending Order : 2, 3, 4, 10, 15, 20, 23
\nMedian =10 but the mean is 11.<\/p>\n
