1. What is Desmos Scatter Plot Calculator?

The Desmos Scatter Plot Calculator allows you to plot data points and fit various regression models to visualize relationships between variables. It uses the powerful Desmos graphing calculator engine.

2. How Does the Calculator Work?

The calculator plots your data points and can fit several types of regression models:

• Linear: y = mx + b
• Quadratic: y = ax² + bx + c
• Exponential: y = abˣ
• Logarithmic: y = a·ln(x) + b
• Power: y = axᵇ

3. Importance of Scatter Plots and Fitting

Details: Scatter plots help visualize relationships between variables. Regression fitting quantifies these relationships and can be used for prediction and analysis.

4. Using the Calculator

Tips: Enter your data as x,y pairs (one per line). Select the type of fit you want to apply. The calculator will plot your points and show the best-fit curve.

5. Frequently Asked Questions (FAQ)

Q1: What format should I use for data points?
A: Enter one x,y pair per line, separated by comma or space (e.g., "1,2" or "1 2").

Q2: How many data points can I plot?
A: Desmos can handle hundreds of points, but for best performance keep it under 1000.

Q3: Can I drag points after plotting?
A: Yes! Click and drag any data point to adjust its position.

Q4: How accurate is the fitting?
A: Desmos uses advanced algorithms to minimize error. R² values are shown for linear fits.

Q5: Can I save my plot?
A: Use the Desmos calculator's built-in share or export features (top-right corner).
