StatsPL Sims is a collection of easy-to-use, interactive simulations to explore statistics. StatsPL Sims was developed for College students taking an Intro to Stats (Stats 101) course, but is also suitable for high school students taking statistics. The following simulations are currently included: -Simple Random Sampling -Frequency Tables vs. Histograms -Histogram Explorer -Central Limit Theorem -Dice Roller -Confidence Intervals -Regression Line Game -Regression Line Explorer -Correlation Coefficient (R) -Normal Distribution -Binomial Distribution -Chi Square Distribution -F Distribution -T Distribution Over the next months, we will add more simulations on additional topics, such as: -One-sample t-test -Two-Sample t-test

Make a use of this standard deviation calculator app to attain the results for standard deviation calculations right now: In the context of statistics, the term standard deviation (SD) refers to the variation or dispersion of the data set of values. A lower SD (also called estimated value) shows that the data points exist very close to the origin. Whereas a higher value of it leads the data points to disperse over a wider range of the values. Use this standard deviation app to determine the standard deviation and variance with a single click. With the help of SD, you can easily find how close the sample mean is to the actual mean of the population. You can use this standard deviation calculator app for to generate absolute outputs. Calculate Standard Deviation of A Set of Values: The SD is calculator on the basis of the following terms: Count of Values: It is the number of the values in the data set. Total Sum of Values: Summation represents the addition of all the values that are given in the data set Standard Mean: It refers to the average of all the values in the set of values. Use this mean and standard deviation calculator to find the mean instantly. Variance: The actual dispersion of data from the mean position is called variance. You can work for the variance with the help of this variance calculator. Coefficient of Variance: The amplitude of the data dispersion about the mean is known as coefficient of variance. Standard Error of Mean: The approximate deviation of the population from mean is known as standard error of mean. This standard error calculator helps you to estimate the actual error of mean precisely. SD helps you in performing various statistical calculations with larger data sets. Now there’s no need to stick with daunting statistical formulas to proceed with SD calculation as our variance and standard deviation calculator does all in a few clicks. Apart from the formulas that are difficult to remember, it is a better practice to use this app for absolutely. How Does It Work? This mean absolute deviation calculator app determines the following terms: Standard Deviation Count of Values Total Sum of Values Mean of The Values Variance Coefficient of Variance Standard Error of Mean (SE) Other Features Includes: User-Friendly Interface An easy to use keyboard with a particular key to enter repetition of same number with one single tap Versatile input box that enlarges as you write data point values Most accurate statistical results The standard deviation tells you how wide and curved the graph will be. If you know the above mentioned terms, you have everything that you need in actual for determining standard deviation. Also for the sake of you people, standard deviation calculator is designed to find accurate output corresponding to the terms defined. Hope it will help you for sure.

Verdict
The clearest difference is in-app purchases: StatsSims at none against Calculate Standard Deviation's 1. StatsSims also leads on ads (none vs shown) and update cadence (every 2 months vs every 7 months). Calculate Standard Deviation's advantage is rating (4.5 vs 4.2) and ratings volume (62 vs 5). On price, review sentiment and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Calculate Standard Deviation sells 1 one-off in-app purchase. StatsSims asks for nothing beyond the download.
Calculate Standard Deviation holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Calculate Standard Deviation has 62 ratings behind it against 5, so its average is the more settled of the two. Written reviews split almost evenly too, at 50% and 50% positive.
StatsSims ships an update every 2 months, Calculate Standard Deviation every 7 months. The most recent releases landed on June 11, 2026 and September 22, 2026 respectively.
