You have the lists of how many students got certain scores on the tests. The scores are grouped into ranges like 10-20,20-30 and so on . Based on the given data Find the value of N​



Answer :

Answer:

To determine the value of \( N \), which typically represents the total number of students, you need to sum the frequencies of students in each score range.

Here’s how you can find \( N \):

1. **Identify the frequency distribution**: You have a list of score ranges and the number of students (frequency) in each range.

For example, suppose your data looks like this:

- 10-20: 5 students

- 20-30: 10 students

- 30-40: 15 students

- 40-50: 20 students

- 50-60: 10 students

- 60-70: 5 students

2. **Sum the frequencies**: Add the number of students in each range to get the total number of students.

\[ N = 5 + 10 + 15 + 20 + 10 + 5 \]

3. **Calculate the sum**:

\[ N = 5 + 10 + 15 + 20 + 10 + 5 = 65 \]

So, the value of \( N \) is 65.

If you provide the specific frequency distribution data, I can calculate the exact value of \( N \) for your case.
