Q2. Differentiate between the following pairs of terms:
- (a)) Geometric mean and Harmonic mean (100 words)
- (b)) Positive Correlation and Negative Correlation (100 words)
- (c)) Global alignment and Local alignment (100 words)
- (d)) PAM and BLOSUM (100 words)
- Geometric Mean: for growth rates and multiplicative averages.
- Harmonic Mean: for rates, speeds, and ratios with constant numerator.
- Positive Correlation: variables move in the same direction.
- Negative Correlation: variables move in opposite directions.
Answer: Here's a differentiation between the specified pairs of terms, essential in Biostatistics and Bioinformatics: **(a) Geometric mean and Harmonic mean** Geometric Mean (GM) is suitable for data that grows exponentially or involves rates of change, such as population growth, interest rates, or average percentages. It is calculated as the nth root of the product of n values. For example, if values are 2, 8, the GM is √(2 × 8) = √16 = 4. Harmonic Mean (HM) is appropriate when dealing with rates or...
