Q

A scale of measurement that has the features of nominal and ordinal scales plus it contains equal intervals between variables. It has no absolute zero point; it is theoretically possible to have negative values on this scale.

24
Q

A type of variance where the scores have a high variability

A

High variance

25
Q

A type of variance where the scores are so close to each other

A

Low Variance

26
Q

It is equal to the difference between the highest and lowest score. Quick but gross description of the spread of scores.

A

Range

27
Q

equal to the square root of the average squared deviation about the mean

A

Standard Deviation

28
Q

a very useful measure of variation because each score’s distance from the mean of the distribution is factored into its computation

A

Standard Deviation

29
Q

equal to the arithmetic mean of the squares of the difference between the scores in a distribution and their mean square of SD

A

variance

30
Q

Distance of each score from the mean

A

Deviation

31
Q

The average distance of the scores from the mean

A

Standard Deviation

32
Q

The greater the value of the variance of _______the more that the data/numbers are scattered or far away from each other in a given distribution.

A

standard deviation

33
Q

nature and extent to which score symmetry of a data is absent

A

skewness

34
Q

This skew means few high scorers and most scores are on the lower end
-yung central tendency nasa lower end spectrum ng scores

A

Positive skew/ Right Skew

35
Q

If the data of the final exam of your students is in positive skew what does that mean?

A

Mahirap yung test, di effective yung nagturo, maraming low scorers

36
Q

This type of skew means few low scorers, most scores are on the higher end

Central tendency ay nasa positive side, yung skew nasa negative side

A

Negative Skew/ Left Skew

37
Q

It is a type of kurtosis in which scores are distributed almost equally through the higher and lower end.,

meaning malaki yung variance ng score

-iba-iba yung scores, wala nang similarities at hindi na ma-describe yung performance ng group

A

PLATYKURTIC-

38
Q

It is a type of kurtosis in which scores are mostly center, with few higher scores in the higher or lower end: pare-parehas lang yung scores

-Masyadong naka squeezer yung performance ng group sa isang score, masyadong homogenous

A

LEPTOKURTIC

39
Q

It is the ideal kurtosis. Sakto lang, well distributed at the same time may degree of sameness

A

MESOKURTIC

40
Q

Kapag ang sample is symmetrical, meaning mesokurtic, and then yung skewness absent and meaning perfectly balanced ito ay may properties ng_____

A

NORMAL CURVE

41
Q

It is the raw score that has been
converted from one scale to another scale

A

Standard score

42
Q

set of scores na may sariling pre determined mean and may pre determined standard deviation

A

standard scores

43
Q

one of the famous standard scores is____?

A

Z-scores

44
Q

It is a measure of the proportion of examinees who answered the item correctly.

A

item difficulty

45
Q

The higher the difficulty, the ____ the item.

A

Easier

46
Q

Item difficulty index should range from

A

0.30 - 0.70

47
Q

An item with difficulty index higher than .70 means____

A

item is too easy

48
Q

An item with difficulty index lower than .30 means___

A

item is too difficult

49
Q

True or false. The higher the difficulty index the better

A

False

50
Q

True or false. The higher item difficulty means an item is easy

A

True

51
Q

What is the symbol of item difficulty?

A

(p)

52
Q

This indicate how adequately an item separates or discriminates between high scorers and low scorers on an entire test.

A

Item Discrimination

53
Q

compares performance on a particular item with performance in the upper and lower regions of a distribution of continuous test scores.

A

Item Discrimination

54
Q

In item discrimination, they posses the target ability.

A

Upper group AKA masters

55
Q

In item discrimination, they do not posses the target ability

A

Lower group AKA non-masters

56
Q

The item-discrimination index should be at least ____

A

.30

57
Q

the item is easy for the upper group and difficult for the lower group.-

A

High item discrimination index

58
Q

Both the lower group and the upper group are getting the correct answer in the item

A

Low item discrimination index

59
Q

The item is difficult for the upper group but easy for the lower group

A

Negative item discrimination index
