# Row statistics

> For the complete documentation index, see [llms.txt](https://kotlin.github.io/dataframe/llms.txt).

API reference: [rowSum](https://kotlin.github.io/dataframe/api-docs/core/org.jetbrains.kotlinx.dataframe.api/row-sum.html), [rowMean](https://kotlin.github.io/dataframe/api-docs/core/org.jetbrains.kotlinx.dataframe.api/row-mean.html), [rowMin](https://kotlin.github.io/dataframe/api-docs/core/org.jetbrains.kotlinx.dataframe.api/row-min.html), [rowMax](https://kotlin.github.io/dataframe/api-docs/core/org.jetbrains.kotlinx.dataframe.api/row-max.html), [rowStd](https://kotlin.github.io/dataframe/api-docs/core/org.jetbrains.kotlinx.dataframe.api/row-std.html), [rowMedian](https://kotlin.github.io/dataframe/api-docs/core/org.jetbrains.kotlinx.dataframe.api/row-median.html), [rowPercentile](https://kotlin.github.io/dataframe/api-docs/core/org.jetbrains.kotlinx.dataframe.api/row-percentile.html)

The following [statistics](summarystatistics.html) are available for `DataRow`:

* `rowSum`

* `rowMean`

* `rowStd`

These statistics will be applied only to values of appropriate types, and incompatible values will be ignored. For example, if a [dataframe](dataframe.html) has columns of types `String` and `Int`, `rowSum()` will compute the sum of the `Int` values in the row and ignore `String` values.

To apply statistics only to values of a particular type, use `-Of` versions:

* `rowSumOf<T>`

* `rowMeanOf<T>`

* `rowStdOf<T>`

* `rowMinOf<T>`

* `rowMaxOf<T>`

* `rowMedianOf<T>`

* `rowPercentileOf<T>`
