QUARTILES

A type of data that has been sorted into groups called classes.

• grouped data

• ungrouped data

In a cumulative frequency distribution table, is being referred by the 'number (quantity) of data in each class interval'?

• Class Interval

• Frequency

• Lower boundary

How to obtain the value of lower boundary (LB) of each class interval?

(Note: UM - Upper Limit, LM- Lower Limit)

• LB = UM + 0.5

• LB = LM - 0.5

Based on the table given, what is the value of x?

• 12

• 14

• 16

• 18

Refer to the table as shown, what is the class interval in the given table?

• 3

• 4

• 5

• 6

Refer to the table as shown, find the total frequency of the given table.

• 10

• 20

• 30

• 40

What is the formula for getting the quartiles for grouped data?

• 
• 

The following are measures of position EXCEPT

• Quartiles

• Deciles

• Percentiles

• Addition

The score points which divide a distribution into four equal parts.

• Percentile

• Decile

• Quartile

If the first quartile of the given data is 20 what does it mean?

• This means that 25% of the students scored lower or equal to 20.

• This means that 15% of the students scored lower or equal to 20.

• This means that 10% of the students scored lower or equal to 20.
