In details briefly distinguish between the following items 1. Informal vs standardized test 2. Individual vs group test 3. Mastery vs survey test 4. Speed vs power test 5. Verbal vs performance test?

1. Informal vs standardized test:
- Informal tests are typically created by teachers or educators and are not standardized, meaning they may vary in content and format. They are often used for formative assessment and to gauge student understanding in a more casual setting. Standardized tests, on the other hand, are created by testing companies and are administered under controlled conditions. They are used for summative assessment and to compare students' performance on a national or international level.

2. Individual vs group test:
- Individual tests are administered to one person at a time and are designed to assess an individual's abilities or knowledge. Group tests, on the other hand, are administered to a group of people simultaneously and are used to assess the group's overall performance or to compare individuals within the group.

3. Mastery vs survey test:
- Mastery tests are designed to measure a student's mastery of a specific set of skills or knowledge. They are often used to determine whether a student has achieved a certain level of proficiency in a subject. Survey tests, on the other hand, are more general and are used to gather information about a student's overall knowledge or abilities in a particular subject area.

4. Speed vs power test:
- Speed tests are designed to measure how quickly a person can complete a task or solve a problem. They are often used to assess processing speed and efficiency. Power tests, on the other hand, are designed to measure a person's overall cognitive ability or intelligence. They typically involve more complex problems and are not timed.

5. Verbal vs performance test:
- Verbal tests assess a person's ability to understand and use language, including reading, writing, and speaking skills. They are often used to measure verbal reasoning and communication abilities. Performance tests, on the other hand, assess a person's ability to perform specific tasks or skills, such as solving puzzles, assembling objects, or completing physical tasks. They are often used to measure non-verbal reasoning and problem-solving abilities.

1. Informal vs Standardized Test

- Informal test: Created by the teacher or instructor for specific students or a class. Typically does not have established norms or reliability measures.
- Standardized test: Developed by experts, administered under controlled conditions, and scored using predetermined standards. Results can be compared across students and groups.

2. Individual vs Group Test

- Individual test: Administered to one person at a time, allowing for individualized attention and observation.
- Group test: Administered to multiple people simultaneously, offering efficiency and cost-effectiveness.

3. Mastery vs Survey Test

- Mastery test: Assesses whether students have achieved a specific level of proficiency in a subject area. Typically scored as pass/fail.
- Survey test: Provides a general overview of a student's knowledge or skills in multiple subject areas. Typically scored on a scale.

4. Speed vs Power Test

- Speed test: Emphasizes completing a large number of questions in a limited time frame. Measures processing speed and efficiency.
- Power test: Allows ample time for students to respond to each question. Measures problem-solving abilities and depth of knowledge.

5. Verbal vs Performance Test

- Verbal test: Assesses abilities in areas such as reading comprehension, vocabulary, and written expression. Typically involves written or spoken language.
- Performance test: Assesses abilities through hands-on tasks, demonstrations, or observations. Does not rely heavily on reading or writing skills.
