z = (x – ?) / ?

Where *z* is the z-score, *x* is the data point, *?* is the mean, and *?* is the standard deviation. By plugging in the values, you can determine how many standard deviations a data point deviates from the mean. A positive z-score indicates that the data point is above the mean, while a negative z-score indicates that it is below the mean.

Understanding z-scores is crucial for statistical analysis as they allow us to compare and interpret data across different datasets. They help identify outliers, determine the significance of a data point, and make informed decisions based on statistical analysis. By using accurate z-score calculators, such as those mentioned in this article, you can easily calculate z-scores and streamline your data analysis process.

Table 1 provides an example of how z-scores are calculated for a dataset consisting of exam scores. The mean score is 80, and the standard deviation is 10. By applying the formula, we can calculate the z-score for each individual’s exam score. The z-scores indicate how each student’s score compares to the average performance in the dataset.

Student | Exam Score | Z-Score |
---|---|---|

Student 1 | 75 | -0.5 |

Student 2 | 90 | 1 |

Student 3 | 82 | 0.2 |
