In basic statistics, students are required to calculate different statistical measures of a set of numbers. With this app, the following statistical measures will be made available to you after you enter a set of numbers: - Number of terms - Total sum - Mean (Average) - Mode - Median - Range - Population Standard Deviation (SD) - Population Variance - Sample Standard Deviation (n-1) - Sample Variance (n-1) Unlimited number of data points is supported. However, in this lite version, negative and decimal numbers are not supported. People should get the full version for negative and decimal number support.
Probability
Calculate probabilities, find percentiles, and visualize probability density or mass functions for a wide range of continuous and discrete statistical distributions. Explore common distributions like normal, binomial, Poisson, and many more.
- Compute probabilities
- Determine percentiles
- Plot probability density function
- Plot probability mass function
- Supports 10+ continuous distributions
- Supports 5+ discrete distributions

Verdict
The clearest difference is review sentiment: Probability at 97% against Statistics Calculator Lite's 40%. Probability also leads on rating (4.9 vs 2.4) and update cadence (every 3 months vs every 12 months). Statistics Calculator Lite's advantage is price (Free vs $1.99) and device support (3 vs 1). On ads, in-app purchases and monetization model there is nothing between them.

Statistics Calculator Lite is free to download; Probability costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Probability holds the better App Store score, 4.9 against 2.4. That said, the two scores are not equally well evidenced: Probability has 193 ratings behind it against 18, so its average is the more settled of the two. Written reviews point the same way: 40% of Statistics Calculator Lite's written reviews are positive against 97% of Probability's.
Statistics Calculator Lite ships an update every 12 months, Probability every 3 months. The most recent releases landed on October 5, 2026 and October 13, 2026 respectively.
