Unit Code: FPM507

Unit Name: Statistics in Forestry

Description: Theory: Basic concepts of forest statistics ? its scope, variable statistics, types and sources of data, classification and tabulation of data, construction of frequency distribution, tables, graphic representation of data, simple, multiple component and percentage, bar diagram, pie diagram, histogram, frequency polygon and frequency curve average and measures of location, mean, mode, median, percentiles, for raw and grouped data. Dispersion: Range, standard deviation, variance, coefficient of variation for raw and grouped data. Probability: Basic concept, additive and multiplicative laws. Theoretical distributions, binominal, poison and normal distributions. Sampling: Basic concepts, sampling vs. complete enumeration parameter and statistic, sampling methods, simple random sampling and stratified random sampling. Tests of Significance: Basic concepts, tests for equality of means, and independent and paired t-tests, chi-square test for application of attributes and test for goodness of fit of mendalian ratios. Computer application: Introduction to computers and personal computers, basic concepts, MS Excel, SPSS and MS PowerPoint. Practical: Construction of frequency distribution table and its graphical representation, histogram, frequency polygon, frequency curve, bar chart, simple, multiple, component and percentage bar charts, pie chart, mean, mode for row and grouped data, percentiles, and median for row and grouped data, coefficient of variation, ?t? test for independent variants, paired ?t? test, chi-square test for contingency tables and theoretical ratios, correlation and linear regression. Application of MS Excel, SPSS and MS Powerpoint in forestry.
