  2. STATISTICAL TREATMENT OF ANALYTICAL DATA • 3.1.1 Errors in Chemical analysis: Types of errors-Determinate and Indeterminate errors-Constant and Proportionate errors, Absolute and Relative error-Minimization of errors • 3.1.2 Measures of central tendency and dispersion : • Measures of central tendency-Mean, Median, Mode. • Measures of dispersion- Deviation, Average deviation, Relative average deviation ,Range , Standard deviation, Variance, Correlation coefficient and Relative standard deviation (Numerical problems expected)

  3. Any measurement involves the interaction of following three components ERROR

  4. True Value Observed Value Difference between Error

  5. These types of errors obtained due to classical methods as these methods involves no. of steps. • Methodic Errors • MnNH4PO4 ---- Mn2P2O7 +2NH3+H2O

  6. 3.1.2 Measures of central tendency and dispersion : • Measures of central tendency-Mean, Median, Mode. • Measures of dispersion- Deviation, Average deviation, Relative average deviation ,Range , Standard deviation, Variance, Correlation coefficient and Relative standard deviation (Numerical problems expected)
