The use of data analytics has become more widespread in all industries due to the emergence of massive data and market driven demands. Predictive analytics is increasingly popular with data analytics as more and more organizations are becoming aware of the importance of predicting future values. Forecasting is also important in the call center to optimize workload. With such content, companies use predictive analytics and various methodologies of predictive models, including regression analysis. Many factors can influence the increase in calls, and one of the most common are advertising campaigns. In my thesis, I predicted the number of calls based on advertising campaigns with linear regression analysis. I have found that linear regression is a suitable method for predicting the number of calls. The results showed that there is a positive correlation between the number of calls and advertising campaigns, which is statistically significant in the monthly and weekly period. I used the obtained results with the help of Erlang's calculator to show the optimization of the schedule in the call center.
