Survival Rate by Gender

• Female: 74.2%
• Male: 18.9%

• A bar plot was created using Plotly to visualize the survival rate by gender on the Titanic.
• The graph shows the survival rate as a percentage for both male and female passengers.
• Visual enhancements were applied, including percentage formatting and displaying the survival rate values outside the bars.

• We have selected features Pclass, Sex, Age, SibSp, Parch, Fare, and Embarked to predict the target variable Survived.
• Categorical variables were converted to numeric using one-hot encoding.
• Missing values in Age and Fare were filled with their respective medians.
• The dataset was split into training and testing sets with an 80-20 split.
• An SVM model with a linear kernel was trained on the training set.
• The model achieved an accuracy of approximately 78.21% on the test set.

Key Points from the Exploratory Data Analysis

1. Dataset Overview:
   • The dataset contains information about Titanic passengers, including features like PassengerId, Survived, Pclass, Name, Sex, Age, SibSp, Parch, Ticket, Fare, Cabin, and Embarked.
2. Missing Values:
   • Significant missing values in Age (177), Cabin (687), and a few in Embarked (2).
3. Summary Statistics:
   • Average age: ~29.7 years.
   • Majority of passengers were male (577 out of 891).
   • Most passengers embarked from port 'S' (644 out of 889).
   • Fare ranged from 0 to 512.
4. Visualizations:
   • Age Distribution: Majority of passengers are between 20-40 years old.
   • Fare Distribution: Most fares are below 50, but there are some high outliers.
   • Survival Rate by Class: Higher survival rate for 1st class passengers.
   • Survival Rate by Gender: Higher survival rate for females.
   • Survival Rate by Embarkation Port: Slightly higher survival rate for passengers who embarked from port 'C'.

Exploratory Data Analysis on Titanic Survival

1. Survival Rate by Age:
   • The survival rates vary across different age groups with noticeable patterns in certain age ranges.
2. Survival Rate by Fare:
   • Higher fares seem to have a correlation with higher survival rates.
3. Survival Rate by Number of Siblings/Spouses Aboard (SibSp):
   • The survival rate appears to fluctuate with the number of siblings/spouses aboard.
4. Survival Rate by Number of Parents/Children Aboard (Parch):
   • The number of parents/children aboard also shows variability in survival rates.

• Survival rates by age and gender: Visualizations indicate that female passengers had higher survival rates across various age groups compared to male passengers.
• Survival rates by class and gender: Female passengers also had higher survival rates across different passenger classes compared to males.
