We created a statistical study to predict the deaths of Corona virus (Covid-19) in the Kingdom of Saudi Arabia and the factors affecting it. Where, where we can predict Corona virus deaths by building a multiple linear regression model for new cases, new tests and a rigor index. We used the R program for all of our research calculations. At the beginning of our study, we collected the required data for a statistical study, after which the data were cleaned, the missing values ​​were removed, the variables identified and the variables correlated with each other, then. Then we tested the normal state of the data using the T test and the F test on the data, and then we adopted the regression model and predictpredicted new data. Finally, we reached the goal of our study.
