measures of skewness; skewed to the left
negatively skewed
23
measures of skewness; thin end tail of the graph goes to the left part of the curve
negatively skewed
24
measures of skewness; most of the scores of the students are above the mean
negatively skewed
25
measures of skewness; possible reason of high scores
1. students are smart 2. enough time to finish exam 3. test item are very easy 4. effective instruction 5. students are prepared for the exam
26
measures of skewness; skewed to the right
positively skewed
27
measures of skewness; test was difficult
positively skewed
28
measures of skewness; most of the scores are low
positively skewed
29
measures of skewness; pre-test
positively skewed

measures of skewness; mean>median>mode
positively skewed
31
measures of skewness; skewed to the left
negatively skewed
32
measures of skewness; test was easy
negatively skewed
33
measures of skewness; most of the scores are hig
negatively skewed
34
measures of skewness; post-test
negatively skewed
35
measures of skewness; mode>median>mean
negatively skewed
36
measures of skewness; is a special kind of symmetric distribution
normal distribution
36
measures of skewness; determined using the values of the mean and standard deviation (kurtosis)
normal distribution
37
Properties of normal distribution
1. curve has a single peak 2. bell shaped curve symmetrical to the mean 3. the end tails of the curve extended indefinitely in both sides 4. the shape of the curve will depend on the values of the mean and standard deviation (kurtosis)

41
indicates where a score is in relation to all other scores, performance of an individual
measure of relative position
42
they make it possible to compare the performance of an individual on two or more different test
measure of relative position
43
measure of relative position; PSZT
1. percentile rank 2. stanines 3. Z-score 4. T-scores
44
measure of relative position; PSZT percentage of the examinees, scored below the score of interest
Percentile rank
45
measure of relative position; PSZT also known as standard nine
stanines
46
measure of relative position; PSZT ranging from 1-9
stanines
47
measure of relative position; PSZT the distribution of raw scores is divided into nine parts
stanines
48
stanines; 1
Very low
49
stanines; 2, 3
Below average
50
stanines; 4 5 6

51
stanines; 7 8
above average
52
stanines; 9
very high
53
measure of relative position; PSZT number of standard deviation units a score is above or below the mean
Z-Score
54
Z Score; PN
1. positive z-score 2. negative z-score
55
Z Score; PN above the mean
positive z-score
56
Z Score; PN below the mean
negative z-score
57
Formula of Z-score
Z= (Score-mean)/standard deviation
58
measure of relative position; PSZT a mean of 50 and a standard deviation of 10
T-Score
59
Formula of T-Score
T=10z + 50
60
61
these describe the degree of relationship or correlation between the two variables
Measure of relationship
62
Measure of relationship; PNN
1. positive correlation 2. negative correlation 3. no correlation
63
Measure of relationship; PNN direct relation, one variable increases the other also increases
positive correlation
64
Measure of relationship; PNN scatter gram, upper right to lower left
positive correlation
65
Measure of relationship; PNN indirect/inverse relation
negative correlation
66
Measure of relationship; PNN one variable increase the other variable decreases
negative correlation
67
Measure of relationship; PNN upper left to lower right
negative correlation
68
Measure of relationship; PNN no relationship
no correlation
