The table gives the mean and standard deviation of four data distributions.

\begin{tabular}{|l|r|r|}
\hline
& Mean & Standard Deviation \\
\hline
Distribution 1 & 22 & 0.2 \\
\hline
Distribution 2 & 21 & 0.8 \\
\hline
Distribution 3 & 19 & 1.2 \\
\hline
Distribution 4 & 20 & 3.2 \\
\hline
\end{tabular}

To determine which distribution has the greatest spread, we need to examine their standard deviations. The standard deviation is a measure of the amount of variation or dispersion in a set of values. The higher the standard deviation, the greater the spread of the distribution.

We have the following standard deviations:
- Distribution 1: 0.2
- Distribution 2: 0.8
- Distribution 3: 1.2
- Distribution 4: 3.2

Among these values, 3.2 is the greatest standard deviation.

Thus, Distribution 4 has the greatest spread.

Therefore, the correct answer is:
```
4
