Question 1

The act of assigning numbers or symbols to
characteristics of things according to values.

Answer 1

Measurement

Question 2

Types of Scales

Answer 2

Nominal Scale, Ordinal Scale, Interval Scale, Ratio Scale

Question 3

involves classification or
categorization based on one or more distinguishing
characteristics, where all things measured must be
placed in mutually exclusive categories.

Answer 3

Nominal Scale

Question 4

Classification, Ranking and NO ZERO
POINT

Answer 4

Ordinal Scale

Question 5

Contain equal intervals

Answer 5

Interval Scale

Question 6

Has true zero point

Answer 6

Ratio Scale

Question 7

A set of test scores arrayed for recording or study.

Answer 7

Distribution

Question 8

A straightforward, unmodified accounting performance that
is usually numerical.

Answer 8

Raw Score

Question 9

All scores are listed
alongside the number of times each score occurred.

Answer 9

Frequency Distribution/ Simple Frequency Distribution

Question 10

Class intervals replace the actual test
scores.

Answer 10

Grouped Frequency Distribution

Question 11

Graphs used in Frequency Distribution

Answer 11

Histogram, Bar Graph

Question 12

It is equal to the sum of observations divided by the number of
observations.

Answer 12

Arithmetic Mean

Question 13

The middle score of the distribution
REMEMBER
If the total number of scores is an odd number, the median will be the
score that is exactly at the middle.

Answer 13

Median

Question 14

frequently occurring (paulit-ulit) score in a distribution of scores.

Answer 14

Mode

Question 15

Equal to the difference between the highest and lowest scores

Answer 15

Range

Question 16

A distribution of scores can be divided into four parts such that 25 percent of the test scores occur in each quarter.

Answer 16

Quartile and Interquartile Range

Question 17

A measure of variability equal to the measure of square root of
variance.

Answer 17

Standard Deviation

Question 18

Relatively few scores fall at the high end of the distribution.
Test is difficult

Answer 18

Positive Skweness

Question 19

Relatively few scores fall at the low end of the distribution.
Test is easy

Answer 19

Negative Skewness

Question 20

Types of Kurtosis

Answer 20

Leptokurtic, Mesokurtic, Platykurtic

Question 21

Sharp peak, heavy tails (more outliers).

Answer 21

Leptokurtic

Question 22

Normal shape, moderate tails (typical distribution).

Answer 22

Mesokurtic

Question 23

Flat peak, light tails (fewer outliers).

Answer 23

Platykurtic

Question 24

The (blank) is perfectly symmetrical with no skewness.
Because it is symmetrical, the mean the median, and the mode all
have the same exact value.

Answer 24

Normal Curve

Question 25

A raw score that has been converted from one scale to another
scale where the latter scale has some arbitrarily set mean and
standard deviation.

Answer 25

Standard Scores

Question 26

conversion of a raw score into a number indicating
how many standard deviation units the raw score is below or above
the mean of the distribution.

Answer 26

Z Scores
