This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.
When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:
summary(cars)
## speed dist
## Min. : 4.0 Min. : 2.00
## 1st Qu.:12.0 1st Qu.: 26.00
## Median :15.0 Median : 36.00
## Mean :15.4 Mean : 42.98
## 3rd Qu.:19.0 3rd Qu.: 56.00
## Max. :25.0 Max. :120.00
You can also embed plots, for example:
Note that the echo = FALSE parameter was added to the
code chunk to prevent printing of the R code that generated the
plot.
La estadística descriptiva es la parte de la estadística que se encarga de organizar, resumir y presentar datos mediante números y gráficos, sin hacer predicciones.
Sirve para responder preguntas como:
Supongamos que tenemos las edades de 5 personas:
edades <- c(18, 20, 22, 19, 21)
🔹 Media (promedio)
mean(edades)
🔹 Mediana
median(edades)
🔹 Resumen general
summary(edades)
Con esto podemos describir los datos sin hacer inferencias, solo resumirlos.
