// ================================================================

// Titanic Dataset challenges! 

// Your goal is to write some functions that will extract
// relevant data from the dataset. 

// Write your code here in this file. 

// *************************************
// Test your code by running: `npm test`
// *************************************

// Each of the functions below expects to receive the Titanic data
// as the parameter data. Your goal is to extract the relevant 
// piece of information from the data and return it. 

// =================================================================

// 1 ---------------------------------------------------------------
// Return the total number of passengers. 
// Return a number.

function getTotalPassengers(data) {
	return 0

// 2 ---------------------------------------------------------------
// Return the number of surviving passengers. A passenger survived 
// if their survived property is "Yes".
// Return a number.

	return 0
}

// 3 ---------------------------------------------------------------
// Return the number of passengers who did not survive. A passenger
// Return a number.

function getCasualityCount(data) {
	return 0
}

// 4 ---------------------------------------------------------------
// Return the number of passengers in any class. This function 
// takes the data and the passenger class a string. Fins all of the 
// passengers whose pclass matches and return the count. 
// Return a number

function countPassengersInClass(data, pclass) {

// 5 ---------------------------------------------------------------
// Return the number of survivors in a class. This function takes 
// the data and passenger class. Return only passengers  

function getSurvivorCountForClass(data, pclass) {
	return 0

// 6 ---------------------------------------------------------------
// Return the number of passengers who did not survive in a class.
// This function takes the data and the passenger class and returns 
// the number of passengers who did not survive for that class.

// 7 ---------------------------------------------------------------
// Return the age of the youngest passenger. You'll need to filter
// passenger data where the age is missing.

// 8 ---------------------------------------------------------------
// Return the age of the oldest passenger. 

function getMaxAge(data) {

// Return the number of passengers that embarked at a given stop. 
// Each passenger has a embarked property with a value of: S, C,
// or Q. 

function getEmbarkedCount(data, embarked) {

// 10 ---------------------------------------------------------------
// Return the lowest fair paid by any passenger. The fare is missing 
// for some passengers you'll need to filter this out!

// 11 ---------------------------------------------------------------
// Return the highest fare paid by any passenger. Some of the 
// passengers are missing data for fare.

// 12 ---------------------------------------------------------------
// Return the count of passengers by gender.

// Return the total of all fares paid.

// 16 --------------------------------------------------------------
// Return the average fare paid.

// 17 --------------------------------------------------------------
// Return the median fare. The median is the value equal distance
// from the minimum and maximum values.
