Find the median value and draw two ogives

### Median Calculation
The calculated median is approximately **23.78**.

### Ogives
The plot above shows the two ogives:
- **Less than Ogive**: Plots cumulative frequency against the upper class boundaries.
- **Greater than Ogive**: Plots cumulative frequency against the upper class boundaries, starting from the highest interval.

Both ogives are essential for understanding the distribution of data, and the intersection of the red dashed line with the "less than" ogive represents the median.

Would you like further details on this process, or do you have any other questions? 

### Follow-Up Questions
1. How would you calculate the median if the frequencies were different?
2. What are the uses of ogives in statistical analysis?
3. Can you explain the significance of the cumulative frequency in finding the median?
4. How does the "greater than" ogive differ in interpretation from the "less than" ogive?
5. What other statistical measures could you calculate from the given data?

### Tip
When working with grouped data, always make sure to check if the class intervals are uniform, as it influences the calculation of measures like the median and mean.
