🔴🔴🔴 🔴 Criterion-Related validity ✅ Criterion-related validity refers to the extent to which test scores correlate with a relevant reputed outside criterion ✅ The correspondence between the content to be tested and the content of the test is present ✅ It investigates the correspondence between the scores obtained from the newly-developed test and the scores obtained from some independent outside criteria @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 Face validity ✅ Face validity often is a desirable feature of a test in the sense that it is useful from a public relations standpoint ✅ Face validity to how the test appears the testees , to the teacher ,to the administrator , and to the testing expert ✅ There is no generally acceptable objective procedure @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 Construct validity ✅ Construct validity to the extent to which a test measures a certain trait or theoretical construct ✅ It is a comprehensive phenomenon that comprises the other types of validity ✅ A test is designed to measure a trait ✅ The trait is psychological in this case ✅ The question is about the reality of this trait ✅ So , in short , construct validity refers to the extent to which the psychological reality of a trait , or construct , can be established ✅ More popular that used under different names including : measures of intelligence , critical reasoning , reading comprehension , study , and all kinds of aptitude and attitude ✅ Construct validity asks questions about the reality of these constructs ✅ Determining construct validity could have a crucial influence on the multiplicity of tests ✅ Construct validity is difficult to determine because it requires utilization of sophisticated statistics called factor analysis @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 Content validity ✅ Sometimes called the appropriateness of the test ✅ It refers to the degree of correspondence between the test content and the content of the materials to be tested ✅ Materials including both subject matter content and instructional objective ✅ Content validity as the extent to which a test measures a representative sample of the content to be tested at the intended level of learning ✅ The focus of content validity , then , is on the appropriacy of the sample of elements included in the test ✅ The term appropriacy refers to both the appropriacy of the sample and the appropriacy of the learning level @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 Criterion-related validity including : ✅1)Concurrent validity ✅2)Predictive validity @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 4 kinds of validity : ✅1)Content validity ✅2)Construct validity ✅3)Face validity ✅4)Criterion-related @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 Validity ✅ The second major characteristic of a good test ✅Validity refers to the student extent to which a test measures what it is supposed to measure ✅ Validity is a more test-dependent concept than reliability is @TestingLanguageSkills_FJB

❌❌❌ دوستان عزیز واقعا دوست ندارم تکرار کنم ، بارها گفتم و میگم این فصل مهمترین فصل سوالات استخدامی هست ، لطفا این فصل رو تا می تونید خوب مطالعه کنید ، به محض اینکه کلاس ها تمام شد کل جلسات رو ، حتما نمونه سوالات استخدامی رو با تکنیک های خاص براتون حل خواهم کرد که بیشتر تسلط پیدا کنید ، بخاطر اهمیت این فصل جلسه بعد هم در مورد آن بحث خواهیم کرد. موفق باشید.

🔴🔴🔴 🔴 KR-21 Method ✅ Other Name : Rational equivalence ✅ It developes to estimate the reliability of test scores ✅ It refers based on the assumption that all items in a test are designed to measure a single trait ✅ It is the most practical , frequently used , and convenient method of Estimating reliability . _ _ . K X(K-X ) (KR - 21) r=( .........)(1- ..............) . K - 1 KV Where : K= the number of the items in a test _ X = the mean score V = the variance @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 Split-Half Method ✅ A test is divided arbitrarily into two halves ✅ Odd and even numbered items and two scores for each testee are obtained , one for each half ✅ Second , the two half-test scores are correlated with one another to obtain a reliability coefficient ✅ Such a coefficient relates to the reliability of only half of the test ✅ For calculating Split-Half , we need to use the Spearman - Brown formula . 2( r half ) ✅ r (total) = ...................... 1 + ( r half ) @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 Parallel-Forms Method ✅ To avoid the complexities of the test-retest method , educators developed the parallel-forms method ✅ In the parallel-forms method , however , two similar , or parallel forms of the same test are administered to a group of examinees just once ✅ Then correlation coefficient between the scores obtained from the two forms will be an estimate of test score reliability ✅ Although this method alleviate the problem of two administrations , it creates another problem ✅ Constructing two parallel forms of a test is not an easy task ✅ Two parallel forms of a test should demonstrate certain statistical characteristics @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 Test-Retest Method ✅ If a test is given twice to the same subjects and it yields similar results on the two administrations , the test is reliable ✅ There are practice effects in addition to memory and administrative problems ✅ Time limits @TestingLanguageSkills_FJB

🔴🔴🔴 🔴 Methods of Estimating Reliability ✅1)Test -Retest Method ✅2)Parallel-Forms Method ✅3)Spilt-Half Method ✅4)KR-21 Method @TestingLanguageSkills_FJB

❌❌❌ با سلام جلسه هفدهم آزمون سازی امشب ساعت 24 برگزار می شود.

❌❌❌ دوستان عزیز توجه کنید فصل ششم مهمترین فصل آزمون استخدامی است پس لطفا بیشتر روش تمرکز کنید جلسه آینده هم در مورد فصل ششم بحث خواهیم کرد. موفق باشید.

🔴🔴🔴 🔴 Methods of Estimating Reliability ✅1)Test -Retest Method ✅2)Parallel-Forms Method ✅3)Spilt-Half Method ✅4)KR-21 Method ❌❌توجه : جلسه بعد هر چهار مورد رو مفصل توضیح خواهیم داد. @TestingLanguageSkills_FJB

🔴🔴🔴 ✅ for example : If the V of a test is 4 and its reliability is 0.64 , what is the standard error of measurement of test ? (سراسری ارشد 84 ) ❌1) 1.4 ❌2) 1.6 ❌3)1.8 ✅4)1.2 Solve : 2 V = SD SD= Sx Or , SD = جذر V SD = جذر 4 SD = 2 Then : SEM = Sx ✖️ (1 - r ) جذر عبارت SEM = 2 ✖️ ( 1 - 0.64 ) جذر SEM = 2 ✖️0.36 جذر SEM = 2 ✖️ 0.6 SEM = 1.2 @TestingLanguageSkills_FJB
