We will employ a systematic approach involving calculations, formulas, and tables to quantify and analyze the results.

Materials and Methods:

Materials:
- Four different hand soaps (A, B, C, and D)
- Petri dishes
- Agar plates
- Sterile cotton swabs
- Bacterial culture
- Ruler
- Incubator
- Stopwatch
Procedure: a. Prepare agar plates with bacterial culture. b. Divide each plate into four sections for each soap. c. Apply a standardized amount of each soap on the designated sections.

d. Use sterile cotton swabs to spread bacteria evenly on each section. e. Incubate plates at a controlled temperature for 24 hours. f. Measure the inhibition zone diameter for each soap.

Calculations:

Inhibition Zone Diameter:
- Use the formula: IZD=D−(D0+Ds)/2
- Where IZD is the inhibition zone diameter, D is the total diameter, D0 is the diameter of the soap application, and Ds is the diameter of the soap application site.
Antibacterial Activity Index:
- Calculate the Antibacterial Activity Index (AAI) using the formula: AAI=IZD×100/D0
Statistical Analysis:
- Calculate the mean and standard deviation of inhibition zone diameters for each soap.
- Perform a one-way ANOVA to determine if there are statistically significant differences among the soaps.
- If significant, conduct post-hoc tests to identify specific differences.

Interpret the results, discussing the effectiveness of each soap based on inhibition zone diameter and Antibacterial Activity Index.
