Proportion of scores calculator

WebbSal used a simple shortcut. A z table indicates the proportion of the area of the distribution TO THE LEFT of a given z score. Given that normal distributions are by definition symmetric around their means, if we're looking for the area of just one tail in the positives, we can either subtract the proportion given by the z table from 1, or simply look at the … Webb2 feb. 2024 · If you've got a data set and want to perform statistical calculations on it, our 99% confidence interval calculator is a good place to start.

WebbSo, that's the proportion. If you thought of it in percent, it would be 0.62% scores higher than Ludwig. Now, that makes sense 'cause Ludwig scored over two standard deviations, two and a half standard deviations above the mean. So, our answer is 0.0062. So, this is going to be 0.0062.
