This is the name of the value found when you add up all the data values and then divide by the number of values you added

This is the mnemonic for the trigonometric ratios

This mathematical term has both magnitude and direction.

This is a name for the middle number in a set of ordered numbers.

We use these units to measure angles

This is the speed your speedometer would read in mph if you were traveling down the highway at 25 m/s. Hint: 1 mile is approximately 1600 m.

This is the name for the spread of the data from the mean

The key used to find the angle in the calculator

This is your reaction time if you were to drop a ruler, and it falls a distance of 20 cm before you catch it.

This is the mean (or average) of Aaron's scores of 4, 5, 5, 2 and 4.

The reason for the angle of elevation to be equal to the angle of depression

Light travels from air (n1 = 1.00) into an optical fiber with an index of refraction of n2 = 1.44. The incoming angle θ1 is 22o. This is the angle of refraction inside the fiber.
