# Aufgabe

In welchem Datensatz, $x1, x2, x3, x4$, gibt es am meisten Variation?



```{r echo=FALSE}
set.seed(42)
d <- tibble(
  x1 = rnorm(10, mean = 0, sd = .1),
  x2 = rnorm(10, mean = 0, sd = 1),
  x3 = rnorm(10, mean = 0, sd = 10),
  x4 = rnorm(10, mean = 0, sd = 100),

Datensatz x1:

```{r}
d %>% 
  select(x1) %>% 
  display()
```

```{r echo=FALSE}
gghistogram(d, x = "x1")
```


Datensatz x2:

```{r}

```




Datensatz x3:

```{r}
d %>%

```


```{r echo=FALSE}

```






Datensatz x4:

```{r}

  display()
```


```{r echo=FALSE}
