                   9.   If a negatively skewed distribution has a mode of 60, which statement if true in this relation?

              B.   Fill in the blanks.
                   1.   Data are of two types            and               .

                   2.   A case is an           .
                   3.   The               is the value that appears most often in a given list of numbers.

                   4.   A               has no numerical or quantitative meaning, it simply  refers  to a quality or characteristic of
                       something.
                   5.   The shape of data distribution in a graph is described by its    and their symmetry, their tendency to
                                     , or their             .
                   6.                 techniques include both manual analysis and automated data exploration software.

                   7.                 is defined as the sum of the squares of the deviation from the mean.
              C.   State whether the following statement is True or False.
                   1.   In the right-skewed distribution, the median and mean are less than the mode.

                   2.   While measuring intervals, the distance between attributes is important.
                   3.   In nominal measurement, attributes can be ordered.

                   4.   The level of measurement refers to the relationship between the cases.
                   5.   Pie charts can condense a large dataset in visual form.

              A.   Short answer type questions.
                     1.  Differentiate between positive and negative correlation.
                   Ans.           Positive Correlation                         Negative Correlation

                         Variable change is in the same direction.  Variable change is in opposite directions.
                         If one variable increases, so do the other   If one variable increases, the other decreases; and if one
                         and vice-versa.                       variable decreases, the value of the other variable increases.
