FaridFaal · Answer

introduction:
this analysis will focus on the socio-economic variables that impacted the survival of passengers aboard the titanic. specifically, we will examine the impact of one nominal variable (passenger class), one ordinal variable (age), and one interval variable (fare) on the likelihood of survival. additionally, we will explore the interactions between these variables to gain a deeper understanding of the factors that influenced survival rates.
discussion:
passenger class:
passenger class, a nominal variable with three categories (1st, 2nd, and 3rd class), had a significant impact on survival rates. of the 216 first-class passengers, 63% survived the disaster. this is in stark contrast to the 47% survival rate of second-class passengers and the mere 24% survival rate of third-class passengers. this suggests that those in higher socio-economic classes had a greater chance of survival.
age:
age, an ordinal variable, also played a role in survival rates. children under the age of 15 had the highest survival rate, with 61% surviving. conversely, adults aged 15-50 had a survival rate of 35%, while those over 50 had a survival rate of just 27%. this trend may be due to the "women and children first" protocol followed during the evacuation of the ship.
fare:
fare, an interval variable, was another important factor in survival rates. passengers who paid higher fares were more likely to survive than those who paid lower fares. the survival rate for passengers who paid the highest fares (over $100) was 63%, while the survival rate for those who paid less than $50 was just 22%. this may be due to the fact that those who paid more for their tickets were more likely to be in first-class and therefore had a better chance of survival.
interaction between passenger class and age:
when we consider the interaction between passenger class and age, we see that the survival rate for children under the age of 15 varied greatly depending on their socio-economic status. first-class children had a survival rate of 87%, while third-class children had a survival rate of just 35%. this suggests that passenger class had a greater impact on the survival of children than age did.
interaction between passenger class and fare:
when we consider the interaction between passenger class and fare, we see that the survival rate for first-class passengers who paid the highest fares was 83%. this is in contrast to the 14% survival rate for third-class passengers who paid the lowest fares. this interaction highlights the fact that socio-economic status played a significant role in determining who survived the disaster.
impact of socio-economic variables on survival:
when we consider all three socio-economic variables together, we see that passenger class had the greatest impact on survival rates, followed by fare and then age. first-class passengers who paid the highest fares and were under the age of 15 had the greatest chance of survival.
conclusion:
in conclusion, our analysis shows that socio-economic variables such as passenger class, age, and fare played significant roles in determining who survived the titanic disaster. first-class passengers who paid the highest fares and were under the age of 15 had the greatest chance of survival. these findings highlight the importance of socio-economic status in determining one's fate during a disaster and serve as a reminder of the inequalities that exist in our society.
