i need you change my answer use another words , use your own words don't copy and paste please.. (I want to redraft the solution).. pleaaaaase quqlye please :(((( When we build a new measurement tool as a “questionnaire”, we need to make sure that the questionnaire is “valid” and “reliable”. In this article we will discuss the concept of validity and reliability. The validityRefers to the degree to which a measurement tool “questionnaire” measures what it supposed to measured....

Question 21 The extent to which 2 assessments measure the same concept at the same level of difficulty is considered to have which type of reliability? (Hint-it may take into consideration split half reliability or dividing the assessment into 2 halves and testing the correlation between the 2 parts) Inter/intra-rater reliability An equivalence or alternative form of reliability Homogeneity Test-retest reliability Question 22 This is used when inherent order is needed to rank categories. An example of data collected would...

Sometimes when you are sick, your forehead feels really warm. You might have fever. How can you find out whether you do? By taking your temperature, of course. But what temperature should the thermometer show if your're healthy? Is this temperature the same for everyone? Several years ago, researchers conducted a study to determine whether the "accepted" value for normal body temperature, 98.6°F, is accurate. They used an oral thermometer to measure the temperatures of a random sample of healthy...
