To calculate five number summary in R, you can use **fivenum()** function. This function gives *minimum*, *maximum*, *median*, *1st quartile* and *3rd quartile* value of dataset.

The following method shows how you can do it with syntax.

**Method: Use fivenum() Function**

```
fivenum(data)
```

The following example shows how to use **fivenum()** function in R.

## Use fivenum() to Calculate Five Number Summary

Let’s see how we can calculate five number summary of data frame:

```
# Create data frame
df <- data.frame(Machine_name=c("A","B","C","D","E","F","G","H"),
Pressure=c(78.2, 78.2, 71.7, 80.21, 80.21, 82.56, 72.12, 73.85),
Temperature=c(35, 36, 36, 38, 32, 32, 31, 34))
# Calculate five number summary of data frame
d <- fivenum(df$Temperature)
# Print five number summary of data frame
print(d)
```

Output:

```
[1] 31.0 32.0 34.5 36.0 38.0
```

The output shows minimum value is 31.0, Q1 is 32.0, the median is 34.5, Q3 is 36.0, and the maximum value is 38.0.
