Which value indicates that a test item is very difficult?

0.3

This is because difficulty indices range from 0 to 1, where lower values indicate more difficult items. A value of 0.3 means that only 30% of the students answered the item correctly, making it a challenging question.

Which item discrimination value shows that an item is acceptable?

0.35

Discrimination indices range from -1 to +1, where higher positive values indicate better discrimination. Generally:

1. 30 or above is considered acceptable or good.

Below 0.20 often indicates poor discrimination and may need revision. Thus, 0.35 is in the acceptable range.

0.41

The good item is the one with the highest discrimination value, as higher values indicate better discrimination between high and low performers. The correct option is 0.41, which represents a good discrimination value.

Which objective is served by evaluating the values of item

discrimination to identify a suitable test item?

0.48

The question seems to be about identifying the objective served by evaluating item discrimination values, not selecting a numerical value. Evaluating item discrimination helps in identifying test items that effectively distinguish between high and low-performing students. If you're asking for the best discrimination value in this context, the suitable test item would be the one with the highest discrimination value, which in the given options is 0.48.

What does "norm-referenced interpretation" refer to?

Comparison to a group Which aspect is the main focus of item analysis?

Item performance Which value represents the item difficulty for the easiest test item?

0.9

Item difficulty is measured on a scale from 0 to 1, where higher values indicate easier items. A value of 0.9 means that 90% of test-takers answered the item correctly, making it the easiest item among the given options.

from?

0.2-1.00

Discrimination power is considered acceptable if the value is 0.2 or higher. Values closer to 1 indicate excellent discrimination, meaning the item effectively differentiates between highperforming and low-performing test-takers. Items with values below 0.2 may need to be revised or discarded.

0.50

An excellent item typically has an item discrimination value of 0.40 or above, which indicates strong differentiation between high-performing and low-performing test-takers.

0.0

The value of item difficulty for the most difficult test item is 0.0, as per the explanation provided in Classical Test Theory (CTT) where item difficulty is expressed as the proportion of examinees who respond correctly to an item. The closer the value is to 0.0, the more difficult the item.

0.1

The value of item difficulty for the most difficult test item is 0.1, as it indicates that only 10% of examinees answered the item correctly, making it highly difficult.

0.9

The value of item difficulty for the easiest test item is 0.9, as it indicates that 90% of examinees answer the item correctly, making it the easiest

0.8

The value of item difficulty for the easiest test item is 0.8, as it indicates that 90% of examinees answer the item correctly, making it the easiest

Scoring is a time consuming process in marking of:

answers Which of the following values indicates a poor item in terms of

discrimination?

0.17

To determine which value indicates a poor item in terms of discrimination, the discrimination index typically ranges from -1 to +1, where:

A value closer to +1 indicates a good item, meaning it effectively differentiates between high and low performers. A value closer to 0 or negative indicates a poor item, as it fails to discriminate effectively.

1. 48, 0.26, and 0.35 indicate moderate to good discrimination.
2. 17 indicates poor discrimination.

Which value represents the item difficulty for the most difficult test

item?

0.2

The item difficulty index ranges from 0 to 1, where:

A value closer to 0 indicates a very difficult item. A value closer to 1 indicates an easier item.

Thus, the most difficult test item would have an item difficulty value closest to 0.2.

The correct answer is 0.2.

0.48

determine the outstanding item?

The aim of assessing item discrimination is to identify items that effectively differentiate between high and low achievers. A higher discrimination value indicates a more effective item.

1. 48 represents the highest discrimination value, making it the most

outstanding item.

determine the outstanding item?

To determine the outstanding item using item discrimination, you assess how well an item differentiates between high-ability and low-ability testtakers. The ideal item discrimination value typically exceeds 0.4, signifying excellent discrimination. Acceptable discrimination levels start from 0.2, with values from 0.3 to 0.39 considered good. Among the options provided, 0.48 is the most likely to represent an outstanding item because it exceeds the threshold for excellent

Which aspect does the difficulty level of an item determine?

Ease or

There are two widely perceived theories in psychosocial measurement,

classical test theory (CTT) and:
