Examples of concept testing in the following topics:
-
- Concept testing is important for evaluating consumer responses to a product before market introduction.
- The concept generation portions of concept testing are generally qualitative.
- Moore and William (1982), in a literature survey and review of concept testing methodology, point out that concept tests have failed to account for changes between the concept tested and the communication describing the benefits of the product which embodies the concept.
- Using focus groups to generate user feedback is one method of going about concept testing.
- Explain concept testing, its disadvantages, and alternative methods used to evaluate consumer behavior toward new concepts
-
- Development involves setting product specifications as well as testing the product with intended customer groups to gauge their reaction.
- The testing process usually begins with the concept test.
- The product concept is a synthesis or a description of a product idea that reflects the core element of the proposed product.
- The second aspect of market development involves consumer testing of the product idea.
- The product itself can be exposed to consumer taste or use tests.
-
- Each Boundless concept has associated assessment items that test the concept's learning objective.
- Every Boundless content module follows a three-part structure: a learning objective, a concept (the supporting text), and assessment items.
- The assessment items are designed to test whether a student has achieved the learning objective for a given concept.
- Explain the role of assessment items in testing a Boundless learning objective
-
- The full text is the heart of an concept.
- The brief is a one-sentence summary at the top of a concept page that provides the most condensed summary of the material presented in the the full text—the main takeaway from that concept.
- The key points include three to five bullet points that provide a more detailed summary of the concept.
- The key terms are the important vocabulary words a student should know after reading a concept.
- All key terms are also programmatically turned into flashcards, which students can practice at any time at the level of the concept, the section, or the chapter to test their comprehension.
-
- Our concept of intelligence has evolved over time, and intelligence tests have evolved along with it.
- He created and published the first IQ test in the United States, the Stanford-Binet IQ test.
- Cattell created the Culture-Fair Intelligence Test.
- This test is a nonverbal group test typically used in educational settings, designed to measure the reasoning ability associated with g.
- Because of the Flynn effect, IQ tests are recalibrated every few years to keep the average score at 100; as a result, someone who scored a 100 in the year 1950 would receive a lower score on today's test.
-
- A significant proportion of the products of conception are lost naturally in the first trimester, especially in the first month.
- A pregnancy test attempts to determine whether a woman is pregnant.
- Qualitative blood tests generally have a threshold of 25 mIU/mL, and so are less sensitive than some available home pregnancy tests.
- Most home pregnancy tests are based on lateral-flow technology.
- However, testing for EPF is expensive and time-consuming.
-
- Test if the percentage of U.S. students who take advanced placement exams is more than 6.6%.
- In statistical hypothesis testing, the alternative hypothesis and the null hypothesis are the two rival hypotheses which are compared by a statistical hypothesis test.
- The concept of a null hypothesis is used differently in two approaches to statistical inference, though the same term is used, a problem shared with statistical significance.
- The concept of an alternative hypothesis forms a major component in modern statistical hypothesis testing; however, it was not part of Ronald Fisher's formulation of statistical hypothesis testing.
- Modern statistical hypothesis testing accommodates this type of test, since the alternative hypothesis can be just the negation of the null hypothesis.
-
- These concepts will be discussed in turn.
- Letting "test" represent a parallel form of the test, the symbol rtest,test is used to denote the reliability of the test.
- It can be shown that the reliability of a test, rtest,test, is the ratio of true-score variance to test-score variance.
- where smeasurement is the standard error of measurement, stest is the standard deviation of the test scores, and rtest,test is the reliability of the test.
- The validity of a test refers to whether the test measures what it is supposed to measure.
-
- We considered the t test statistic as a way to evaluate the strength of evidence for a hypothesis test in Section 7.4.2.
- This concept – considering the amount of variability in the response variable explained by the explanatory variable – is a key component in some statistical techniques.
-
- Case-based learning provides opportunities for richer, deeper exploration of concepts and ideas.
- Students gain experience with analyzing ideas and applying concepts to solve problems or achieve goals as opposed to acquiring abstract knowledge.
- Assessing student learning and evaluating performance requires much more than the traditional multiple-choice or short-answer tests, but clear learning objectives, performance standards and relevant criteria can enable teachers to use a more holistic approach and to better tailor activities to students' needs.
