How to Use an AI Statistics Calculator

Step 1: Input Your Data Enter data using various methods:

CopyExample Dataset: Test scores
85, 92, 78, 95, 88, 76, 91, 84, 89, 93

Or upload CSV/Excel files for larger datasets.

Step 2: Select Analysis Type Choose from:

• Descriptive statistics
• Hypothesis testing
• Correlation/regression
• Probability calculations
• Distribution fitting

Step 3: Detailed Analysis Process

Example: Descriptive Statistics for Test Scores

Step 3.1: Calculate Central Tendency

• Mean: (85+92+78+95+88+76+91+84+89+93)/10 = 87.1
• Median: Sort data → (88+89)/2 = 88.5
• Mode: No repeating values

Step 3.2: Calculate Dispersion

• Range: 95 – 76 = 19
• Variance: Σ(x – mean)²/(n-1) = 42.99
• Standard Deviation: √42.99 = 6.56
• Coefficient of Variation: (6.56/87.1) × 100 = 7.53%

Step 3.3: Calculate Position Measures

• Q1 (25th percentile): 82
• Q2 (50th percentile/Median): 88.5
• Q3 (75th percentile): 92.5
• Interquartile Range (IQR): 92.5 – 82 = 10.5

Step 3.4: Identify Outliers

• Lower fence: Q1 – 1.5(IQR) = 82 – 15.75 = 66.25
• Upper fence: Q3 + 1.5(IQR) = 92.5 + 15.75 = 108.25
• No outliers detected

Step 4: Visualize Results The calculator generates:

• Histogram showing distribution
• Box plot displaying quartiles
• Normal probability plot

Step 5: Interpret and Apply Use insights for decision-making, similar to AI homework helper math for educational contexts.

Use Cases & Examples

Example 1: Hypothesis Testing (Two-Sample t-Test) Problem: “Do students using Method A (mean=85, SD=8, n=30) perform differently than Method B (mean=79, SD=7, n=28)?”

Solution process:

1. State hypotheses:
   • H₀: μ₁ = μ₂ (no difference)
   • H₁: μ₁ ≠ μ₂ (difference exists)
2. Check assumptions:
   • Independence: ✓
   • Normality: Sample sizes >30, CLT applies
   • Equal variances: Test using F-test
3. Calculate test statistic:
   • Pooled SD = 7.52
   • SE = 1.98
   • t = (85-79)/1.98 = 3.03
   • df = 56
4. Find p-value:
   • p = 0.0037 (two-tailed)
5. Conclusion:
   • p < 0.05, reject H₀
   • Significant difference between methods
   • Method A shows higher performance

Example 2: Correlation and Regression Problem: “Analyze the relationship between study hours (x) and test scores (y)”

Data:

CopyHours: 2, 3, 4, 5, 6, 7, 8
