To determine how many data points will be in the center group for the median-median line, we need to follow the steps of the median-median line calculation:

1. **Sort the Data**: Arrange the data points in order of the x-values.

2. **Divide into Three Groups**: Split the sorted data into three groups (A, B, C) with an equal number of points, or as close to equal as possible. If you have an odd number of points, the middle group will have slightly more points.

The data you provided appears to be in pairs (x, y) but isn't formatted clearly. Let's interpret what you provided and define a dataset. Based on your values, it looks like this:

```
Data points:
(2.5, 66)
(17.5, 88)
(19, 109)
(119, 131)
(211.5, 915)
(1116, 1520)
(2021.5, 242)
(25.5, 252)
(21, 28)
```

**Sorting the X-values:**
```
2.5, 17.5, 19, 25.5, 21, 28, 119, 211.5, 1116, 1520, 2021.5, 242
```

However, we still need clearly defined x and y pairs.

**Counting the Data Points:**
Count the total number of data points. From your list, it looks like you have 10 pairs.

So, distribute them into three groups (A, B, C):

- If there are 10 points, it can be divided as follows:
- Group A: 3 points
- Group B: 4 points (the center group)
- Group C: 3 points

**Thus, the center group has 4 data points for the median-median line calculation.**
