? Trends in Biostatistics with Practical by Dr. Tripurari Mishra, published by Mahaveer Publications, is a comprehensive textbook designed as per the CBCS and NEP-2020 syllabus for B.Sc. 5th and 6th Semester Life Science Honours (DSE) courses offered by universities across Assam and India.

This book offers a balanced blend of theoretical principles and practical applications of biostatistics, enabling students to understand and analyze biological data effectively. It covers the fundamental concepts of data collection, organization, and representation, along with the measures of central tendency, dispersion, and variability essential for biological research.

Major topics include:

• Data and sampling techniques in biological research

• Frequency distribution and graphical representation

• Measures of central tendency (Mean, Median, Mode)

• Measures of dispersion (Range, Variance, Standard Deviation, Coefficient of Variation)

• Probability distributions – Binomial, Poisson, and Normal

• Tests of significance – t-test, F-test, and Chi-square test

• ANOVA (One-way and Two-way)

• Correlation and regression analysis

• Biostatistical applications in life sciences

The practical section provides step-by-step exercises on data handling, statistical testing, and result interpretation using real biological examples, preparing students for both laboratory and field-based data analysis.
