Quiz Answer Key and Fun Facts

1. When carrying out a phone survey, people keep hanging up on you and "avoiding" your survey

Answer: Non-response Bias

When you're missing individuals in a population survey you could get very misleading results. One common type of bias is non-response where participants either choose not to respond or are unable to give their feedback.

2. You "initially assume" that your lasagna is 400 calories but you're going to test to see if it's more calories

Answer: Null Hypothesis

When running a hypothesis test, the null hypothesis is the given assumption. In statistics we say the parameter is equal to some value and test that the alternative hypothesis is more, less, or different from the assumption.

3. The three test scores are 100, 90, and 50! You needed to "average" more than 75

Answer: Mean

Mean and average both mean the sum of all data points divided by the number of data points. In the following example 100 + 90 + 50 = 240 and this divides by 3 equals a mean of 80. You passed!

4. I need to roll doubles with two dice to win the game, what's the "chance"?

Answer: Probability

Probability is the likelihood of an event happening. This answer is a value between 0 (impossible) and 1 (certainty). In the dice example, there are 36 possible ways for two dice outcomes and six of these are doubles where both dice match. This has a 6/36 probability.

5. Election polls show the results could be "within" five percent in either direction, so it's too early to call the winner

Answer: Margin Of Error

The sample is trying to predict the population value. Given the predicted parameter value, researchers give a margin of error, a percentage they are confident the population's true value would fall between.

6. The doctor says your baby's weight is normal, it fits the typical "bell curve" of expected weights

Answer: Normal Distribution

A normal distribution curve does resemble a bell curve. Many sets of data follow an Empirical Rule where the mean is down the middle of the curve and within one standard deviation in each direction 68% of all data lies. Within 2 or 3 standard deviations from the mean, our data fall between 95% and 99.7% respectfully.

7. Who wins the prize? Let's put all the names in a hat and everyone has an "equal chance" to win.

Answer: Simple Random Selection

A simple random selection gives every member of the population an equal and known chance of selection. Choosing from a hat, using a random number generator, or flipping a coin are all basic examples of a simple random selection.

8. Let's do a phone survey, but some in the group have "unlisted" numbers. That wouldn't be fair to leave them out

Answer: Undercoverage

If a survey process leaves out a group of individuals during the survey method, this is called undercoverage. Since the whole population isn't capable of being chosen we may get misleading results. In this scenario, anyone with the unlisted numbers would be missed by our method.

9. Too many mosquitos on the back porch; what would "happen if" we lit a citronella candle? Would we see fewer pesky bugs?

Answer: Experiment

An experiment is when you apply a treatment to a scenario and see how or if the results change. A treatment in our mosquito situation would be adding a citronella candle to see if that causes a reduction in mosquitos.

10. It hasn't rained in weeks then we suddenly get four inches of rain on Wednesday. Wow, that is a "unexpected huge difference".

Answer: Outlier

An outlier is an extreme deviation from the mean. When something is two or three standards above or below the mean, we classify it as an outlier. If our average rainfall is less than an inch in a day and then we suddenly get four inches, that would be unusual and considered an outlier.
