In statistics, the mode is the value that is repeatedly occurring in a given set. We can also say that the value or number in a data set, which has a high frequency or appears more frequently, is called mode or modal value. It is one of the three measures of central tendency, apart from mean and median. For example, the mode of the set {3, 7, 8 ...a) Create a table of grouped frequency distribution for the number of classes k = 9. b) Construct a histogram of relative frequencies of the flat areas. c) From the specified values estimate the sample mean and the variance. d) From the middle values of the intervals and from their frequencies estimate the sample mean and the variance.Median, in statistics, is the middle value of the given list of data when arranged in an order. The arrangement of data or observations can be made either in ascending order or descending order. Example: The median of 2,3,4 is 3. In Maths, the median is also a type of average, which is used to find the centre value.Math homework can often be a challenging task, especially when faced with complex problems that seem daunting at first glance.
