Answer:
The achievement test had high split-half reliability.
Explanation:
The achievement test had high split-half reliability.
Split-half reliability is a measure of a test's internal consistency, or the extent to which different parts of the test are measuring the same thing. High split-half reliability indicates that the test is consistent and that a person's score on one half of the test is a good predictor of their score on the other half of the test.
The fact that the correlation between correctly answered questions on the odd and even questions was extremely high indicates that the test is consistent in measuring the same construct or trait, which supports the notion of high split-half reliability.
It should be noted that:
- Predictive validity refers to the extent to which a test can predict future performance or behavior.
- Test-retest reliability refers to the consistency of a test's results over time.
- Content validity refers to the extent to which a test measures what it is supposed to measure.
- Criterion validity is the extent to which a test's scores are related to other variables that are considered to be criterion or standards.

According to the law of universal gravitation, any two objects are attracted to each other. The strength of the gravitational force depends on the masses of the objects and their distance from each other. Many stars have planets around them. If there were no gravity attracting a planet to its star, the planet's motion would carry it away from the star. However, when this motion is balanced by the gravitational attraction to the star, the planet orbits the star. Two solar systems each have a planet the same distance from the star. The planets have the same mass, but Planet A orbits a more massive star than Planet B. Which of the following statements is true about the planets?
The statement that is true about the planets is option B. Planet A orbits its star faster than Planet B.
What is the law of universal gravitation?According to the law of universal gravitation, any two objects are attracted to each other.
Planet A will experience a stronger gravitational force from its more massive star than Planet B will experience from its less massive star, even though the planets are the same distance from their respective stars.
This is because the strength of the gravitational force between two objects is directly proportional to the mass of those objects and inversely proportional to the square of the distance between them.
Since the planets have the same mass and are the same distance from their stars, the only factor that changes is the mass of the stars. So, the gravitational force experienced by Planet A will be greater than that experienced by Planet B.

Note that the early branch of psychology that focused on our human need for love and acceptance and on environments that nurture or limit personal growth was called Humanistic Psychology.
What are the tenets of Humanistic Psychology and why is it important?Humanistic psychology is a viewpoint that stresses people's subjective experiences and personal progress. Its tenets include the belief in people's inherent goodness, the value of self-actualization, and the necessity of healthy, empathetic connections.
It is significant because it emphasizes the individual's unique experiences and promotes self-exploration and self-acceptance.
This approach influenced the development of numerous types of psychotherapy, including person-centered treatment.
