Answer: test had less than perfect reliability

Explanation: The test score used by the college to predict how a student will perform could be said to have less than perfect reliability.

It shows that the test score can not consistently serve as proof that only students who have above the cut off mark will be good performers in the college.

bearhunter [10]

Answer:

True

Explanation:

While the means to why they invest can be different, most people invest in stocks to provide for their retirement. When you retire, it doesn't mean you suddenly don't have to pay for anything. You'll have to either save a large amount of money or have an investment to draw upon when you retire.

What term describes how a team communicates with one another, deals with conflict, and expresses feelings?
Nat2105 [25]

The term <u>Group dynamics</u> describes how a team communicates with one another, deals with conflict, and expresses feelings.

Group dynamics refers to the processes by which individuals in a team interact with one another. Group dynamic is influenced by the personality and attitudes of members, hierarchies, powers, and perceptions, among others.

The group may be formal (specially organized for a specific purpose) or informal (spontaneous).

Groups proceed through stages of <em>forming</em>, <em>storming</em>, <em>norming</em>, <em>performing</em>, and <em>adjourning</em>. These stages trace the development of how members communicate, deal with conflicts, express feelings, and find common ground so they can attain their best performance.
