What is the difference between Ic and Io, definitionally?

Ic = the intensity of a given quake

Io = a negligible reference of normal waves

200

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.

200

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.

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

What does the Central Limit Theorem state?

Data points may not be normally distributed, but the sample means of that data are normally distributed

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
