1. Absolute and relative spread of measures

NCERT Solutions For Class 11 Statistics Chapter 6 explores additional concepts in this section. NCERT Solutions explained the meaning and definition of  Mean Deviation Coefficient. It also explains the derived formula and gives the meaning of each term in the formula.

1. Lorenz curve

NCERT Solutions For Class 11 Statistics Chapter 6, introduces students to a new topic that is none other than the Lawrence curve. Students learned how to measure variability using sets and means, variances, and more. A curve plotting all these measurements on graph paper is nothing but the Lorenz curve. Students should understand the Lorenz curve in detail.  NCERT Solutions For Class 11 Statistics Chapter 6 also provides information on constructing Lorenz curves. Due to its important role in the field of statistics,  NCERT Solutions For Class 11 Statistics Chapter 6 can be learned as a step-by-step process by which students learn a lot.
