The Normal Distribution
The normal distribution is a probability distribution with a symmetric bell-shaped curve centered at the mean (μ), characterized by its standard deviation (σ). It's used in statistics to model real-world variables like test scores and heights. ScanSolve visualizes and calculates probabilities for your dataset instantly.
How to Approach The Normal Distribution

Input mean and standard deviation
Enter the mean (μ) and standard deviation (σ) of your dataset to define the normal distribution.
- 02
Specify the probability or variable
Choose whether you want to find a probability (P(X ≤ x)) or a specific value (like Z-score).

Frequently Asked Questions
What is a Z-score?
A Z-score measures how many standard deviations an element is from the mean. It standardizes different datasets for comparison.
Why is the normal distribution important?
It's crucial in statistics for finding probabilities and is used to model many natural phenomena due to its occurrence in large datasets.
How do you find probabilities with it?
Probabilities are found using Z-scores and standard normal distribution tables, depicting likelihood for a range of values in the dataset.
