Art of Stat: Explore Data im Vergleich zu Calculate Standard Deviation Nutzung und Statistiken
Statistics calculator for teachers and students of statistics.
The Art of Stat: Explore Data app includes statistical methods for exploring categorical and quantitative data. Obtain summary statistics, contingency tables or correlation coefficients and generate bar- and pie charts, histograms, boxplots (including side-by-side boxplots), dotplots or interactive scatterplots that let you color dots by a third variable. Several example datasets are preloaded for you to explore (including instructions on the statistical analysis), but you can also enter your own data or import a CSV file.
The following methods are implemented:
- Analyzing One Categorical Variable
- Comparing Groups on a Categorical Variable
- Analyzing the Relationship Between Two Categorical Variables
- Analyzing One Quantitative Variable
- Comparing Groups on a Quantitative Variable
- Analyzing the Relationship Between Two Quantitative Variables (Linear Regression)
The app provides:
- Frequency tables and bar and pie charts for exploring one categorical variable.
- Contingency tables, conditional proportions and side-by-side or stacked bar charts for exploring a categorical variable across several groups or the association between two categorical variables.
- Mean, standard deviation and the 5-number summary together with histograms, boxplots and dotplots to explore a quantitative variable.
- Side-by-side boxplots, stacked histograms or density plots for comparing a quantitative variable across several groups.
- Interactive scatterplots with regression lines to analyze the relationship between two quantitative variables. Correlation statistics and linear regression parameters and predictions. Plots of raw and studentized residuals.
The app comes with several example datasets preloaded, which you can directly open in the app to explore the app's various features. You can also type in your own data or upload your own CSV file (which any spreadsheet program can create) and select variables from it. Finally the app includes a basic spreadsheet program called Data Editor to create and edit data.
You can also copy & paste data from a spreadsheet app such as Google Sheets, Excel or Apple’s Numbers app. Several sample datasets are provided.

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.
