\u2013 Statistics of NCERT Solution:<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.1 Introduction<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">With examples, this section discusses the concepts of central tendency, mean, and median [during even and odd numbers of observations]. It introduces the notion of dispersion measurement.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">Measures of central tendency are values that cluster around the middle or center of the distribution. The three terms are mean, median, and mode.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">The mean can be used to find the average marks earned by students in a class.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">The median can be used to obtain the midway value when calculating student height.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.2 Measures of Dispersion<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">This section defines dispersion metrics, including the range, quartile deviation, mean deviation, and standard deviation.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">The relationship between measures of central tendency and measures of dispersion is explained by measures of dispersion. The spread of data, for example, indicates how well the mean represents the data. The mean is not reflective of data if the spread is big.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.3 Range<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">The range, its formula, and an example are all defined in this section.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">Using the set&#8217;s highest and minimum values, the range calculates the variability of scores.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">Batsman A&#8217;s range in a cricket match is 121 \u2013 0 = 121, while Batsman B&#8217;s range is 52 \u2013 22 = 30.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">Range A is greater than Range B. As a result, in the instance of A, the scores are dispersed, whereas in the case of B, they are near together.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.4 Mean Deviation<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">The formula for mean deviation is defined in this section.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">Biologists can utilize the notion of mean deviation to compare different animal weights and determine what is a healthy weight.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.4.1Mean deviation for ungrouped data<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">In this section, we&#8217;ll go through how to calculate the mean deviation for ungrouped data.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">Find the mean, standard deviations, and absolute deviations, then use the mean deviation formula to calculate the solution.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.4.2 Mean deviation for grouped data<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">This section explains how to calculate mean deviation for discrete and continuous frequency distributions using solved examples.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.4.3 Limitations of mean deviation<\/b><\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 12pt;\">If there is a lot of variability in a series, the median will not be a good representation of the data. As a result, the mean deviation derived around such a median is unreliable.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 12pt;\">The mean deviation about the mean is not very specific if the sum of deviations from the mean is bigger than the sum of deviations from the median.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 12pt;\">Further algebraic handling of the obtained absolute mean deviation is not possible. It can&#8217;t be utilized as a reliable indicator of dispersion.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-size: 12pt;\"><b>15.5 Variance and standard deviation<\/b><\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.5.1 Standard Deviation<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">The definitions of variance and standard deviation, as well as formulas and solved examples for discrete and continuous frequency distributions, are covered in this section.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">A group of pupils completed a scientific test. On calculation, the test had an average score of 85 percent. The teacher looked up the standard deviation of the other results and discovered that it was relatively minimal, implying that the majority of the kids scored very close to 85 percent.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.5.2 Shortcut method to find Variance and standard deviation<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">With a few illustrations, this section explains how to calculate the standard deviation in a simplified approach.<\/span><\/p>\n<p><span style=\"font-size: 12pt;\"><b>15.6 Analysis of Frequency Distributions<\/b><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">This section explains how to compare the variability of two series with the same mean, coefficient of variation, and a small number of solved issues.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Following_are_the_concepts_discussed_in_Chapter_15_Statistics\"><\/span><span style=\"font-size: 12pt;\"><b>Following are the concepts discussed in Chapter 15 Statistics:<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 12pt;\">The difference between the maximum and least value of the given data is defined as the range.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 12pt;\">If two series have the same mean, the one with the lower standard deviation is more stable and less scattered.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400; font-size: 12pt;\">The variance is unaffected by adding or subtracting a positive value from each data point in the data collection.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400; font-size: 12pt;\">The solutions provide alternative tactics and clarifications for dealing with problems, allowing the learner to feel confident when taking the first term exam. In addition, dealing with a variety of confusing difficulties improves pupils&#8217; knowledge of mathematical abilities.
