Poisson probability mass function with the specified arguments (0.084224) If mean ≤ 0, POISSON returns the #NUM! error value.Ĭumulative Poisson probability with the specified arguments (0.124652) If x ≤ 0, POISSON returns the #NUM! error value. If x or mean is nonnumeric, POISSON returns the #VALUE! error value. If cumulative is TRUE, POISSON returns the cumulative Poisson probability that the number of random events occurring will be between zero and x inclusive if FALSE, it returns the Poisson probability mass function that the number of events occurring will be exactly x. A common application of the Poisson distribution is predicting the number of events over a specific time, such as the number of cars arriving at a toll plaza in 1 minute.Ĭumulative is a logical value that determines the form of the probability distribution returned. For example, type Area in the header row and the Area column will appear with data. If you're using a table, type a field name in the header row. For example, pick Population.Ĭlick the Insert Data button again to add more fields. Click that button, and then click a field name to extract more information. Select one or more cells with the data type, and the Insert Data button will appear. You'll know they're converted if they have this icon:
If Excel finds a match between the text in the cells, and our online sources, it will convert your text to the Geography data type. With the cells still selected, go to the Data tab, and then click Geography. Later on, this will make extracting online information easier. For example, type a country, state, province, territory, or city name into each cell.Īlthough it's not required, we recommend creating an Excel table. Note: The Geography data type is only available to Worldwide Multi-Tenant clients (standard Microsoft 365 accounts).
