I am so confused by these. If possible please explain. I have included the data set

The data set being used in this assessment includes data collected after the 2009 war ended between Israel and the Hamas militias in the Gaza Strip. One hundred and ninety-eight (180) responses were obtained from a group of students who were exposed to rocket attacks during that period. The variables in the data set include: . ID: Used to indicate the ID# of the participant . age: The age of the individual that responded to the survey (ranges from 19 to 66) . family.income (in thousands): The combined income of the respondent's family in thousands . gender: The gender of the individual that responded to the survey (Female; Male) . family.in.range: Indicates whether or not the participant's family decided to stay in the range of the rockets (Not in rocket range vs. In rocket range) . family.size: The size of the respondent's family (Small, Medium, Large) . anger: The respondent's self-reported level of anger they felt during the war (on a scale of 0 to 100) . fear: The respondent's self-reported level of fear they felt during the war (on a scale of 0 to 100) . perceived.threat: The respondent's self-reported estimate of the likelihood/probability they would experience risky events within the next 12 months (on a scale of 0 to 1)For each of the variables listed in Questions 7 to 10, select the most appropriate central tendency that should be used to represent the data.
