Titanic Survival Dataset - Classification

Updated: Nov 1, 2021

Description :

This dataset provides information on the fate of passengers on the Titanic, summarized according to economic status (class), sex, age and survival. This dataset can be used for classifying passengers into two groups based on whether they survived or not.

Recommended Model :

Algorithms to be used: random forest, svm, logistic regression etc

Recommended Project :

Titanic survival prediction

Overview of data

Detailed overview of dataset:

- Rows = 1309 ( train set: 891, test set: 418)

- Columns= 1 2

PassengerId: Passenger identification number
Survival : Passenger's survival (0= No; 1 = Yes)
Pclass: Passenger's Class (1 = 1st; 2 = 2nd; 3 = 3rd)
name: Passenger's Name
sex: Passenger's Sex
age: Passenger's Age
sibsp: Number of Siblings/Spouses Aboard
parch: Number of Parents/Children Aboard
ticket: Ticket Number
fare: Passenger's Fare (British pound)
cabin: Cabin
embarked: Port of Embarkation (C = Cherbourg; Q = Queenstown; S = Southampton)

NOTE:

pclass: A proxy for socio-economic status (SES):

1st = Upper

2nd = Middle

3rd = Lower

age: Age is fractional if less than 1. If the age is estimated, it is in the form of xx.5

sibsp: The dataset defines family relations in this way:

Sibling = brother, sister, stepbrother, stepsister

Spouse = husband, wife (mistresses and fiancés were ignored)

parch: The dataset defines family relations in this way:

Parent = mother, father

Child = daughter, son, stepdaughter, stepson

Some children travelled only with a nanny, therefore parch=0 for them.
