Statistics, survey research, and scientific data can contain bias.

Explanation:

Statistical data analysis is a powerful tool for creating callsigns and evidence about a study. Data analysis has evolved over time and its importance is increasing. However, the statistics must have their parameters validated, as there are several situations in which bias occurs such as selection bias, sampling error bias, systematic bias, among others. To prevent this from happening, you need to know statistical theory well and choose an appropriate statistical model for your data.
