ITEM ANALYSIS: Item analysis is a statistical technique which is used for selecting and rejecting the items of the test on the basis of their difficulty value and discriminated power. OBJECTIVES OF ITEM ANALYSIS: ---To select appropriate items for the final draft. ---To obtain the information about the difficulty value (D.V) of all the items. ---To provide discriminatory power (D.I) to differentiate between capable and less capable examinees for the items. ---To provide modification to be made in some of the items to prepare the final draft properly (easy to difficult items). STEPS OF ITEM ANAYSIS: 1)- Arrange the scores in descending order. 2)- Separate two sub groups of the test papers. 3)- Take 27% of the scores out of the highest scores and 27% of the scores falling at bottom. …show more content…
5)- Count the non-response (N.R) examinees. USES OF ITEM ANALYSIS: Item analysis is useful for obtaining: --- Difficulty value (D.V). --- Discriminative power (D.P) Difficulty value (D.V): According to J.P. Guilford “The difficulty value of an item is defined as the proportion or percentage of the examinees who have answered the item correctly”. The formula for difficulty value can be written as: D.V = (R.H + R.L)/ (N.H + N.L) • R.H = rightly answered in highest group. • R.L = rightly answered in lowest group. • N.H = no of examinees in highest group. • N.L = no of examinees in lowest group. In case non-response examinees available means, the formula for difficulty value (D.V) can be written as: D.V = (R.H + R.L)/ [(N.H + N.L)-
In this scenario, I have to calculate the quiz scores by adding 94 + 93 + 85 + 0 = 272, and then divide by 4. The average of my quiz score is 68. This is a numeric data. Numerical data are numbers; we can count or measure it (Yakir, 2011).
The purpose of assessment is to ensure that the tutor has a clear understanding of their learners and their individual needs.

Examiners can use the TONI for various purposes. These purposes include estimating aptitude and general intellectual function. Identifying individuals believed to have intellectual impairments. Verifying the validity of referrals for treatment, therapy, or special services. In other words, the assessment is used to measure aptitude and general intellectual function without the need for verbal instructions. In order to administer this test, the examiner will need a basic understanding of mental ability testing and measurement statistics. They should also have a knowledge of the general procedure governing test administration scoring and interpretation. This knowledge is acquired by enrolling in college courses developed to assessment. These courses are typically found in the department of school psychology, special education, speech pathology, educational psychology and counseling. Workshops sponsored by local and state education agencies, professional organization, or private consultants may also help. In Counseling 428 Measurement Issues in Counseling, the different levels and the qualifications of those levels were discussed. The TONI-4 would be classified as in the level B category which “Requires some technical knowledge of test construction and background of the area(s) being assessed. Purchasers must have completed a four-year
The general perception of today’s generation view on introspection is generally assumed globally to have the same meaning. But a deep research into the topic will lead into concluding that the topic has had lots of variations over the years.

In many cases, the additional time and cost to conduct a quantitative analysis is not justified. Some risks with qualitative consequences, e.g. reputation damage, must be transformed into a quantitative amount. Quantitative assessments may be required in some instances, due to regulations, industry norms, or high-risk environments (ISO/IEC, 2009). It is important to be aware that while quantitative assessments look extremely precise, they are only as accurate as the data used to generate the estimate.
