# Single regression

To explore the association between two continuous variables, regression analysis can be used. In this example, a dataset/dataframe called `dat`

contains two continuous variables, `independentVariable`

and `dependentVariable`

.

## SPSS

```
DATASET ACTIVATE dat.
REGRESSION
/DEPENDENT dependentVariable
/METHOD ENTER independentVariable
/STATISTICS COEF CI(95) R ANOVA.
```

## R

```
regr(dependentVariable ~ independentVariable, data=dat);
```

To also order a plot:

```
regr(dependentVariable ~ independentVariable, dat=dat, plot=TRUE);
```
