Question

Determine the best central tendency (mean, median, mode) to represent our data.

• eventid: used to indicate the ID# of the terrorist incident
• country: the country in which the incident took place (e.g., US, Canada, Germany)
• region: the region where the incident took place (e.g., North America, Europe, Asia)
• attacktype: the type of attack used (e.g., kidnapping, bombing, assassination)
• severity: the severity of the incident (i.e., minor, major, catastrophic)
• ransom: whether or not a ransom was demanded (i.e., yes or no)
• ransomamt: the monetary value of the ransom demanded, expressed in millions
• nkill: the total number of fatalities in the incident
• nwound: the total number of people injured in the incident

1. Country?

2. attacktype?

3. ransom?

4. ransomamt?

5. severity?

Answer 1

1. For country, we should check in which country most of the incidents took place. So, we should use mode in this case.

2. In order to measure the central tendency of attack type we can use median. In this case mode can also be used to measure the most frequent attack type.

3..In this case we should be use mode to conclude whether random was demanded in most of the cases.

4. The monetary value of ten random amount can be measured using mean.

5.To check the severity of the incidents we should use median.
