Quick Start

from survey_analyzer import SurveyAnalyzer

analyzer = SurveyAnalyzer()

# Load survey data
analyzer.load_csv('survey_responses.csv')

# Analyze Likert scale question
results = analyzer.likert_analysis('satisfaction', scale_type='agreement')
print(f"Mean score: {results['mean_score']:.2f}")

# Cross-tabulation
crosstab = analyzer.crosstab('age_group', 'product_preference')
print(crosstab)

# Generate report
analyzer.generate_report('survey_report.pdf')

Likert Scale Analysis

Standard Scales

# 5-point agreement scale
analyzer.likert_analysis('satisfaction', scale_type='agreement')
# 1=Strongly Disagree, 2=Disagree, 3=Neutral, 4=Agree, 5=Strongly Agree

# 5-point frequency scale
analyzer.likert_analysis('usage', scale_type='frequency')
# 1=Never, 2=Rarely, 3=Sometimes, 4=Often, 5=Always

# Custom scale
analyzer.likert_analysis('rating', scale_type='custom',
                        labels=['Poor', 'Fair', 'Good', 'Excellent'])

Results

results = analyzer.likert_analysis('satisfaction')
# {
#     'mean_score': 4.2,
#     'median': 4,
#     'mode': 5,
#     'distribution': {1: 2, 2: 5, 3: 15, 4: 40, 5: 38},
#     'percentages': {1: 2%, 2: 5%, 3: 15%, 4: 40%, 5: 38%},
#     'top_2_box': 78%,  # % Agree + Strongly Agree
#     'bottom_2_box': 7%  # % Disagree + Strongly Disagree
# }

Visualization

# Stacked bar chart
analyzer.plot_likert('satisfaction', 'likert_chart.png')

# Compare multiple questions
analyzer.likert_comparison(['quality', 'value', 'service'])
analyzer.plot_likert_comparison(['quality', 'value', 'service'],
                               'comparison.png')

Frequency Analysis

Single Choice

freq = analyzer.frequency_table('age_group')
#          Count  Percentage
# 18-24      45      22.5%
# 25-34      78      39.0%

# 45+        25      12.5%

# Plot
analyzer.plot_frequencies('age_group', 'age_distribution.png')

Multiple Choice

For questions allowing multiple selections:

# Data format: "Option A, Option B, Option C"
results = analyzer.multiple_choice('features_liked', delimiter=',')
#                Count  Percentage
# Price            120      60%
