Measures of Positions, Central Tendency, and Dispersion

We can divide the data set into four quartiles. Similarly, it can also be divided into ten deciles, as well as a hundred percentile.

• True

• False

• There is not enough inform to conclude.

• Sometimes true.

Which among the following is the equivalent of 3rd Quartile?

• D3

• D75

• P75

• None is correct among the choices.

Which of the following statistical tools identify the location of a certain data in a set?

• Measures of Position

• Measures of Central Tendency

• Measures of Dispersion

• None is correct among the choices.

The following ratings were given by the judges to Group A's delicacy.

6, 7, 7, 7, 7, 8, 8, 8, 8, 9, 10, 10

What is Q3 and its corresponding data (x3)?

• Q3 = 9 ; x3 = 9

• Q3 = 8 ; x3 = 8

• Q3 = 8 ; x3 = 9

• Q3 = 9 ; x3 = 8

The following ratings were given by the judges to Group A's delicacy.

6, 7, 7, 7, 8, 8, 8, 8, 8, 9, 10, 10

What is D4 and its corresponding data (x4)?

• D4 = 4 ; x4 = 7

• D4 = 4 ; x4 = 8

• D4 = 5 ; x4 = 7

• D4 = 5 ; x5 = 8

When finding the measures of position, it is not necessary to arrange the data from lowest to highest.

• True

• False

• There is not enough information to conclude.

• Sometimes true.

This measure of central tendency finds the most repeated data value.

• Mean

• Median

• Mode

• None is correct among the choices.

Which measure of central tendency is the most commonly used?

• Mean

• Median

• Mode

• None is correct among the choices.

We can also find the median by calculating the 50th percentile, 5th decile, or 3rd quartile.

• True

• False

• There is not enough information to conclude.

• Sometimes true.

What type of mode is the set of data below?

0, 5, 4, 0, 2, 1, 7, 6, 4, 6,

• Unimodal

• Bimodal

• Trimodal

• Modal
