Based on the image, we have a frequency distribution table for grouped data. The intervals for the data are given along with their respective frequencies. The task is to determine:

1. **Mean**
2. **Median**
3. **Mode**

### Steps to Solve:

#### 1. **Mean (Rata-rata)**:
We use the formula for the mean of grouped dataBased on the image, we have a frequency distribution table for grouped data. The intervals for the data are given along with their respective frequencies. The task is to determine:

1. **Mean**
2. **Median**
3. **Mode**

### Steps to Solve:

#### 1. **Mean (Rata-rata)**:
We use the formula for the mean of grouped 
\[
\text{Mean} = \frac{\sum f_i x_i}{\sum f_i}
\]
Where:
- \(f_i\) is the frequency for each group.
- \(x_i\) is the midpoint of each group (calculated as the average of the class boundaries).

#### 2. **Median (Median)**:
For grouped data, the formula for the median is:
\[
\text{Median} = L + \left( \frac{\frac{n}{2} - CF}{f} \right) \times h
\]
Where:
- \(L\) is the lower boundary of the median class.
- \(n\) is the total number of observations.
- \(CF\) is the cumulative frequency of the class preceding the median class.
- \(f\) is the frequency of the median class.
- \(h\) is the class width.

#### 3. **Mode (Modus)**:
For grouped data, the mode is calculated using the formula:
\[
\text{Mode} = L + \left( \frac{f_1 - f_0}{(f_1 - f_0) + (f_1 - f_2)} \right) \times h
\]
Where:
- \(L\) is the lower boundary of the modal class.
- \(f_1\) is the frequency of the modal class.
- \(f_0\) is the frequency of the class before the modal class.
- \(f_2\) is the frequency of the class after the modal class.
- \(h\) is the class width.

Let's first compute the class midpoints and proceed with the calculations. I'll do that now.

Determine the mean, median, and mode based on the given frequency distribution table.
