Step 1: Project Details
Total budget available for data collection
Available time for data collection
Step 2: Population Characteristics & Study Objectives
Who are you studying?
Total number of units in population (if known)
What is the main question your evaluation seeks to answer?
Are there key subgroups that must be represented? (e.g., gender, age, region)
Step 3: Sampling Method Selection
Choose the method you will use (recommendation above, but you can select differently)
Step 4: Sample Size Calculation
📊 Sample Size Parameters: Configure the parameters below based on your study objectives and precision requirements. Different formulas apply for different study types.
