3. What is Test Item Analysis?
Test Item Analysis is the process of evaluating
the performance of individual test items to
determine their effectiveness in measuring
student learning. It involves analyzing statistical
data to identify problematic items and improve
test quality. The results of test item analysis can
be used to refine test items, improve test design,
and enhance student learning outcomes.
4. Types of Test Item Analysis
There are several types of Test Item
Analysis including Difficulty Index,
Discrimination Index, Point Biserial,
and Distractor Analysis. Each type
provides different insights into the
performance of test items and can help
identify areas for improvement.
5. Di™culty Index
Difficulty Index measures the
proportion of students who answered a
test item correctly. It provides insights
into the overall difficulty of the test and
can help identify items that are too easy
or too difficult.
6. Discrimination Index
Discrimination Index measures the
ability of a test item to distinguish
between high-performing and low-
performing students. It provides
insights into the effectiveness of a test
item in measuring student learning.
7. Point Biserial
Point Biserial measures the correlation
between the performance on a test
item and the overall test score. It
provides insights into the relationship
between individual test items and
overall test performance.
8. Distractor Analysis
Distractor Analysis measures the
effectiveness of incorrect answer
choices in a multiple-choice test item. It
provides insights into the common
misconceptions and errors made by
students and can help improve the
effectiveness of test items.
9. Conclusion
Test item analysis is a critical aspect of test design and can
help improve the quality of assessments. By analyzing
statistical data, educators can identify problematic test items
and refine their assessments to better measure student
learning. We hope that this presentation has provided you
with a comprehensive understanding of test item analysis and
its role in improving student learning outcomes.
