What is the strongest animal in the world, by mass?
The Dung Beetle. They can pull 1,141 times their own body weight.
lnx = 5
x = ?
x = 148.4
What is the difference between Ic and Io, definitionally?
Io = a negligible reference of normal waves
What is the difference between a parameter and a statistic?
A parameter is a number that describes a whole population, while a statistic is a number that describes a sample.
What is the difference between Standard Deviation and Variance?
Standard Deviation is a measure of the dispersion of data, while Variance is the distance from a data point to the mean.
What is the smallest bone in the body?
Stapes / Stirrup, in the inner ear.
log7(3) = x
x =
x = 0.56
If an earthquake in Taiwan clocks in at Magnitude 4.0, and an earthquake in Italy clocks in at Magnitude 5.5, how many times larger was the house quake?
31.6 times larger
Data points may not be normally distributed, but the sample means of that data are normally distributed

Normal Distribution
Gaussian Distribution
Bell Curve
Which continent has the longest coastline?
Asia
loglnx4 = 2
x = 7.4
If an earthquake in Taiwan clocks in at Magnitude 4.0, and an earthquake in Italy (magnitude 1,200 km) clocks in at Magnitude 5.5, what was the intensity in Taiwan?
37.95 km
What is an unbiased estimator?
Approximates the true mean / expected value
“Approaching a limit from the right” means the POI is on the left of your pencil as you trace towards it.
True or False?
The Cheetah is the fastest animal on the earth. Guess how fast it can run in miles per hour. (within ~5 miles per hour)
~64.8 miles per hour
Guess must be between 60 and 70 to count
log100x + logx = 0
x =
x = 1
If an earthquake in Taiwan has an intensity of 3,000 km, and an earthquake in Japan has an intensity of 40,500 km, what is the difference on the Richter's scale?
1.13
These concepts could be considered to be "inversely" related. Why?
- Central Limit Theorem
- Sample Error
Sample error decreases as sample size increases.
CLT bell-shape increases as number of samples increase.
What is the formula for z-score?
z = (value - mean) / stdev
The longest book in the world was created as a cultural commentary on the commodification of comics. Guess either how long it was (within ~2,000 pages will count) or what popular Japanese comic it was.
21,450 pages
19,000 - 23,000 will count as correct
