### Analyzing the Impact of Independent Variables on Prediction Errors**a. Influence of Ignoring Independent Variables**- **Question:** Treating sex of offender as the independent variable, how many errors of prediction will be made if the independent variable is ignored?**b. Error Reduction Through Inclusion of Variables**- **Question:** How many fewer errors will be made if the independent variable is taken into account?**c. Calculating and Discussing Lambda**- **Task:** Combine your answers in (a) and (b) to calculate lambda. Discuss the relationship between these two variables.**d. Comparing Lambda Strength**- **Question:** Which lambda is stronger, the one for sex of offenders/victims or race of offenders/victims (Exercise 5)? **Analysis of Offenders and Victims of Violent Crime**In this section, we examine data from the U.S. Department of Justice for the year 2011, highlighting the relationship between the sex of offenders and victims of violent crime.**Data Table Overview:**The table presents information on violent crimes, classified by the sex of both the offender and the victim. - **Sex of Victim:** - **Male Victims:** - Male Offenders: 3,760 incidents - Female Offenders: 450 incidents - **Female Victims:** - Male Offenders: 1,590 incidents - Female Offenders: 140 incidents**Source:**Data is sourced from the U.S. Department of Justice, Expanded Homicide Data, Table 6, 2011.This data provides insight into the dynamics of violent crime, illustrating that male offenders are more frequently involved regardless of the victim’s sex.

How would I get the degrees of freedom?
