Measures of Central tendency- Mean , median, mode,
Measures of dispersion-Range, Standard deviation, coefficient of variation.
Calculating Measures from an Ungrouped Frequency Table
Approximating Measures from Grouped Data.
Basic probability, conditional probability, concept of independence, Sensitivity, Specificity etc, and Bayes Theorem for predictive probabilities.
Some discrete probability distributions: cumulative probability distribution, Binomial, and Poisson –their mean and variance
Continuous probability distributions: Normal distribution, Standard normal and t distributions.
Sampling with and without replacement, sampling distribution of one and two sample means and one and two proportions.
Statistical inference: Point and interval estimation, Type of errors, Concept of P-value, testing hypothesis about one and two samples means and proportions including paired data – different cases under normality.
