is this event going to happen? An event is the outcome of an experiment. Events can be either independent or
              dependent.

              Variance                                                                                           mean


              Variance is a measure of how much the values in a dataset differ
                                                                                 Variance
              from  the  mean  (average)  value.  It  helps  you  understand  how
              spread out or scattered the data is.
              A high variance means the numbers are spread out widely around
              the mean, while a low variance means the numbers are closer to
              the mean.                                                                                     Data Points
                                                                                                            Mean
              Standard Deviation                                                                            Outlier
                                                                                                            Variance
              Standard  deviation  is  the  square  root  of  the  variance,  and  it
              provides a measure of how spread out the values are in the original units (not squared units, like variance). It gives
              a sense of how “far” the data points are from the mean on average.
              Outlier


              An outlier is a data point that is significantly different from the other points in the dataset. It’s an “exceptional”
              value that is much higher or lower than most of the other values.

                   Purpose: Reinforce the Need of Descriptive Statistics
                   Creating a mind map for Descriptive Statistics (focusing on mean, median, and mode) can help you visualize
                   how these statistical measures are used in various real-life contexts.           [CBSE Handbook]
