1. Statistics Class

2. The sharp –nosed shark consumes shrimp, mollusks and small fishes.

3. Sea Turtles Sea turtles often drown when caught in fishing gear: both nets and loglines. Coastal development can destroy important nesting sites, impact coral reefs, and artificial light from houses and other buildings distracts hatchlings away from the ocean. 

4. The “garbage patches” are areas of marine debris concentration (due to oceanographic features)in the North Pacific Ocean. The term “garbage patches” is a misnomer. There is no island of trash forming in the middle of the ocean nor a blanket of trash that can be seen with satellite or aerial photographs.

6. Coral reefs are found all around the world in tropical and subtropical oceans. They are usually found in shallow areas at a depth of less than 150 feet. However, some coral reefs extend even deeper, up to about 450 feet deep.

7. Variance The squared version of the standard deviation

8. Standard deviation Shows how much variation or dispersion exists from the average

9. *TDC: Theoretical picture of distribution based upon random sampling. Serves as a standard with the actual distributions can be compared.

10. T-Test A t-test is any statistical hypothesis test in which the test statistic follows a Student's t distribution if the null hypothesis is supported.
