Sports Betting & Statistics: How To Use Historical Data To Predict Sports Results
Step 1: Collect Betting Records
The first step to solid betting analysis is gathering accurate and reliable data.
Find Reliable Data Sources
Start by using dependable sources for your betting data. BettorEdge is a great option, as it tracks key metrics across major leagues, such as:
- Bet amounts and odds
- Win/loss outcomes
- ROI by sport
- Performance trends
- Head-to-head results
If you're using traditional sportsbooks, keep detailed records across all platforms. To make this easier, check out the BettorEdge Sports Bet Tracking Template, which offers a standardized way to collect and organize your data.
Once you've gathered accurate data, the next step is to organize it in a way that makes analysis straightforward.
Set Up Data Storage
A well-structured storage system is key to effective betting analysis. Here's a quick guide to what your data should include:
Data Category | Details to Record |
Basic Bet Details | Date, Sport, Event, Bet Type |
Financial Data | Stake Amount, Odds, Payout |
Performance Metrics | Win/Loss, ROI, Streak Data |
Additional Notes | Research, Reasoning, Conditions |
Best practices for organizing your data:
- Keep formats consistent for dates, numbers, and values.
- Add context, such as reasoning behind each bet.
- Regularly back up your data to avoid losing it.
- Update your records as soon as bets are settled.
If you’re using BettorEdge, its analytics tools can automatically organize your betting history and even generate performance charts. For manual tracking, consider using separate spreadsheets or databases for each betting category. This approach helps you spot patterns specific to different sports or bet types.
Step 2: Fix Data Problems
Once you've collected your data, the next step is to address any issues. Even minor errors can throw off your performance analysis.
Fix Data Errors
Here are some common data problems and how to resolve them:
Error Type | Example | Solution |
Duplicate Entries | Same bet recorded twice | Use spreadsheet tools to find and remove duplicates |
Missing Values | Blank odds or stake info | Review your bet history to fill in gaps or flag incomplete entries |
Incorrect Formats | Mixed odds formats (-110, 1.91) | Convert all odds into a single, consistent format |
Calculation Errors | Incorrect ROI calculations | Double-check formulas and automation for accuracy |
If you're using BettorEdge's tracking template, many of these errors are automatically avoided thanks to built-in validation. For manual spreadsheets, make it a habit to regularly check for these issues to ensure your data stays accurate.
Make Data Consistent
Consistency is key when working with betting data. To standardize your records:
- Use the MM/DD/YYYY format for all dates (e.g., 03/09/2025).
- Record amounts in USD with two decimal places (e.g., $100.00).
- Stick to one odds format - American, decimal, or fractional.
- Always use the official team names.
To maintain accuracy, apply these validation rules:
- Stakes: Must be positive numbers.
- Odds: Should match your chosen format.
- Outcomes: Limited to , , , or .
- Dates: Cannot be set in the future.
Export and standardize your data from all platforms as soon as possible. Incorporating regular error checks and audits into your tracking process will help ensure your data remains reliable. With clean and consistent data, you'll be well-prepared to uncover betting trends in the next step.
Step 3: Find Key Patterns
Track Success Rates
Once your data is cleaned, it's time to evaluate your betting performance using these core metrics:
Metric | Formula | Target Threshold |
Win Rate | (Wins / Total Bets) × 100 | Over 52.4% for traditional sportsbooks or 50% for BettorEdge (break-even) |
ROI | ((Profit - Investment) / Investment) × 100 | Aim for a positive ROI |
Profit Margin | (Net Profit / Total Stakes) × 100 | Depends on sport or bet type |
Average Stake | Total Stakes / Number of Bets | Keep it consistent |
Platforms like BettorEdge operate on a peer-to-peer model, removing the vig. This can make it up to 20 times more likely for you to achieve profitability. These metrics are the foundation for identifying patterns that lead to better results.
Spot Winning Patterns
Use your performance metrics to dig deeper into your betting history and find trends that work:
- Performance AnalysisLook at how you perform across different leagues, sports, and bet types (e.g., moneyline, spreads, totals). Pay attention to odds ranges, risk levels, and whether teams are playing at home or away.
- Time-Based PatternsAnalyze trends based on timing. Are certain days of the week or times of day more profitable? Does your performance vary by season? Compare pre-game bets to live betting results.
For the most accurate insights, aim to collect at least three months of consistent data. Regularly review your analytics to adjust your strategy as market conditions shift.

Step 4: Create Data Charts
Make Basic Graphs
Once your data is organized and performance trends are clear, the next move is to visualize those trends. Charts and graphs can highlight patterns that might not be obvious in raw data.
Chart Type | Best For | Examples of Metrics |
Line Graph | Tracking changes over time | Cumulative ROI, bankroll growth |
Bar Chart | Comparing categories | Win rates by sport or bet type |
Pie Chart | Showing proportions | Stake allocation, sport breakdown |
Heat Map | Spotting peak times | Win rates by day or time |
When designing your charts, stick to consistent timeframes to ensure your analysis stays accurate. Tools like BettorEdge can automatically create performance charts, breaking down ROI for major leagues like the NFL, NBA, and MLB.
The next step is picking the right tools to turn these visuals into actionable insights.
Use Analysis Software
Your choice of tools depends on your experience and needs. Here are a few options:
- Excel/Google Sheets: Great for basic chart creation and straightforward data visualization.
- Professional Platforms: BettorEdge offers features like automated ROI tracking, win percentage graphs, sport-specific performance breakdowns, historical trends, and leaderboard comparisons.
- Advanced Tools: For those with coding knowledge, Python libraries like Pandas and Matplotlib can be used to create custom visuals.
Start with simpler tools to build confidence before diving into more complex methods. Keep your charts clean and focused - extra data points can distract from the key takeaways. Update these visuals regularly after each betting session to maintain an accurate view of your performance.
These charts can guide smarter, more informed betting decisions by making trends and patterns easier to understand.
Step 5: Use Data Results
Build Smarter Betting Strategies
Turn data into actionable plans. Use these metrics to fine-tune your betting strategy:
Performance Metric | Action Plan |
Win Rate by Sport | Focus more of your bankroll on sports where you've consistently performed well. |
Time-based Performance | Place bets during timeframes that historically deliver better results. |
Stake Size Impact | Adjust your bet sizes based on past ROI for different stake amounts. |
Market Type Success | Prioritize markets (like spread, moneyline, or totals) where you excel. |
Platforms like BettorEdge report that users applying data-driven strategies see a 5–10% boost in earnings per bet compared to prior results. This gain comes from leveraging detailed analytics and avoiding the traditional house edge.
Once you’ve outlined your plan, keep an eye on your results to refine your approach as needed.
