Question 16: When data is tabulated, what is the indicator of how many data points are included in each class?

Question 17: Which of the following is taken along the Y-axis to draw the ogive curve?

Question 18: Which of the following is correct for the ogive curve?

2. Solution Steps

Question 16:

When data is tabulated into classes, the number of data points in each class is represented by the class frequency.

Therefore, the answer is "শ্রেণির গণসংখ্যা" which translates to "class frequency".

Question 17:

In an ogive curve, the Y-axis represents the cumulative frequency.

Therefore, the answer is "ক্রমযোজিত গণসংখ্যা" which translates to "cumulative frequency".

Question 18:

An ogive curve is a cumulative frequency curve. It always increases (or remains constant). Therefore, it is an ascending or upward-sloping curve.

Therefore, the answer is "ঊর্ধ্বগামী" which translates to "upward".

3. Final Answer

Question 16: ঘ

Question 17: গ

Question 18: ক
