WebOct 31, 2024 · A z-table tells you the area underneath a normal distribution curve, to the left of the z-score. In other words, it tells you the probability for a particular score. To use one, first turn your data into a normal distribution. Then find the matching z-score to the left of the table and align it with the z-score at the top of the table. WebSep 13, 2024 · Finding z = 1.53. Here, a Z-score of 1.53 corresponds to a value of 0.9370 in the table. This means that the area under the curve to the LEFT of 1.53 is 0.9370. Said another way, 93.7% of the data ...

WebStep #2: Using the Z-score formula. In order to calculate the z-score, we will use the following formula. z = (x – μ )/σ. Step #3: Using the inputs parameters in the Z-Score formula. z-score = (70-60)/15 = 0.67. You can use the above Z score calculator to calculate the z score value using the above input parameters. Step #4: Using Z-Table WebYou shouldn't be getting the standard deviation or the mean from a Z-table. The Z-table assumes a mean of 0 and a standard deviation of 1 (hence why we calculate a z-score before going to the table). The table has two uses: 1. Calculate a z-score and find the probability under the curve. 2. Look up a probability and find the z-quantile. 2 comments
