1. Theory Component

1.1 Introduction, Types and Variables of Data
• Introduction and importance
• Data: Meaning and Types- Primary data and secondary data, Discrete data and continuous data
• Variables and their types

1.2 Precision and Accuracy
• Concept of Precision: Mean, median, mode, range, absolute deviation, average deviation, relative average deviation, standard deviation, variance
• Concept of Accuracy: Absolute and relative error
• Measures of Dispersion: Percentiles, Mean deviation, Standard deviation (S.D.) Coefficient of variation

2. Practical Component

Practicals:
(i) Determination of mean, median and mode of titre values of acid base titration (Minimum number titre values = 10).
(ii) Determination of standard deviation and variance of titre values of any complexometric titration (Minimum number titre values = 10).
(iii) Determination of acetic acid in vinegar by potentiometry and calculate absolute and relative error.
(iv) Determination of Absolute deviation, average deviation and relative average deviation from the given data of any experiments of Chemistry.
(v) Determination of absolute and relative error in standardization of Na2S2O3 by using 0.05N K2Cr2O7.
