What is the frequency of the most number of inquiries? What year levels have equal frequency of inquiries? What kind of numerical data is obtained through measuring?

Numerical data is also known as quantitative data.

• Quantitative data

Telephone numbers are used for identification and do not have a meaningful order or numerical value for calculations.

• Nominal data

The tally marks represent the frequency of inquiries for each year level:

• Year Level 7: $\cancel{||||}$ $\cancel{||||}$ $\cancel{||||}$ $\cancel{||||}$ $||$ = 22 inquiries
• Year Level 8: $\cancel{||||}$ $\cancel{||||}$ $\cancel{||||}$ = 15 inquiries
• Year Level 9: $\cancel{||||}$ $||$ = 7 inquiries
• Year Level 10: $\cancel{||||}$ $||$ = 7 inquiries

The most number of inquiries is 22, which corresponds to Year Level 7. The question asks for the frequency itself.

• 22

Year Level 9 and Year Level 10 both have 7 inquiries, meaning they have an equal frequency.

• Year Level 9 and Year Level 10

Numerical data obtained through measuring (e.g., height, weight, temperature) can take any value within a given range.

• Continuous data
