November 14, 2017Help calculating a percentile from a Z-score
There's little value out that far, since essentially nothing is close enough to normal for those numbers to be accurate. For what purpose do you need these values? when you say "percentiles" are you actually looking for the cdf, the ccdf (survivor function), the two-tailed area - outside (-6,6) and (-12,12) - or what? The upper tail areas (ccdf) are: > pnorm(c(6,12),lower.tail=FALSE) [1] 9.865876e-10 1.776482e-33 More on reddit.com

April 4, 2024What is a Z-score?
A Z-score (or standard score) measures how many standard deviations a data point is from the mean. It's calculated as: Z = (X - μ) / σ, where X is the value, μ is the mean, and σ is the standard deviation.

How do you use a Z-score table?
To use a Z-score table: 1) Calculate your Z-score, 2) Find the row matching the first two digits, 3) Find the column for the second decimal place, 4) The intersection gives you the probability or area under the normal curve.

What is a confidence interval?
A confidence interval is a range of values that likely contains the true population parameter. For example, a 95% confidence interval means we're 95% confident the true value falls within that range. Z-scores help calculate these intervals.
