Basic Data Analysis with PSeInt

Now that you have PSeInt installed and ready to go, let's explore some basic data analysis tasks you can perform. We'll start with simple examples and gradually move on to more complex ones.

1. Calculating Descriptive Statistics

Descriptive statistics provide a summary of your data, including measures like mean, median, mode, standard deviation, and variance. Let's write a PSeInt program to calculate these statistics for a given set of numbers.

Algoritmo EstadisticasBasicas
	Definir numeros Como Real
	Definir suma, media, mediana, desviacionEstandar Como Real
	Definir n, i Como Entero

	// Ingresar la cantidad de números
	Escribir "Ingrese la cantidad de números:"
	Leer n

	Dimension numeros[n]

	// Ingresar los números
	Para i <- 1 Hasta n Hacer
		Escribir "Ingrese el número ", i, ":"
		Leer numeros[i]
		suma <- suma + numeros[i]
	FinPara

	// Calcular la media
	media <- suma / n

	// Calcular la mediana (ordenar los números primero)
	Para i <- 1 Hasta n-1 Hacer
		Para j <- i+1 Hasta n Hacer
			Si numeros[i] > numeros[j] Entonces
				Definir temp Como Real
				temp <- numeros[i]
				numeros[i] <- numeros[j]
				numeros[j] <- temp
			FinSi
		FinPara
	FinPara

	Si n MOD 2 = 0 Entonces
		mediana <- (numeros[n/2] + numeros[n/2+1]) / 2
	SiNo
		mediana <- numeros[(n+1)/2]
	FinSi

	// Calcular la desviación estándar
	Para i <- 1 Hasta n Hacer
		desviacionEstandar <- desviacionEstandar + (numeros[i] - media)^2
	FinPara

desviacionEstandar <- RC(desviacionEstandar / n)

	// Mostrar los resultados
	Escribir "Media: ", media
	Escribir "Mediana: ", mediana
	Escribir "Desviación Estándar: ", desviacionEstandar
