See my attached demo for find the central spatial moments, if that's what you want. KSSV's solution gives you the radiometric stats, not spatial stats. For example, the first moment (mean) for intensity will give you the mean gray level whereas for spatial...
the calculation is different for the mean or proportion. When you are asked to find the sample error, you’re probably finding the standard error. That uses the following formula: s/√n. You might be asked to find standard errors for other stats like the mean or proport...
Find the standard deviation (e.g. 8). Divide Step 1 by four (e.g. 8 / 4 = 2). The rule of thumb doesn’t work that well to find a range for small data sets. And it doesn’t work at all if you don’t have data that fits anormal distribution. That’s why you’ll rarely...

but using a TI-84 Plus calculator is easier and more accurate. There are two methods of finding the z-score of a data set: You can use the TI-84 Plus to find the mean and standard deviation and then use the z-score equation, or you can use the TI-84 Plus invNorm function with ...
It can be hard to find the perfect sample size for statistically sound results. Here we reveal methods and tools for effective sample size determination.
To analyze quantitative data, use: Descriptive Statistics: Calculate mean, median, mode, and standard deviation. Cross-Tabulation: Compare different variables to find relationships. Correlation and Regression: Determine the strength and direction of relationships between variables. ...

()to apply thetable.Stats()function from PerformanceAnalytics. Thetable.Stats()function returns a table of statistics for the portfolio, but since we want only standard deviation, we willselect()the Stdev column. Normally,table.Stats()would be called on an xts object, but tidyquant let...
Back to Top Confidence Interval with the Normal Distribution / Z-Distribution If you don’t know your population mean (μ) but you do know the standard deviation (σ), you can find a confidence interval for the population mean, with the formula: x̄ ± z * (σ / √n), Where x̄...
