1. What is the value of the slope of the best fit trends line for the relationship between TDD and the depth of the active layer.

2. If α = 0.05, is this slope statistically significant? (yes/no)

3. Compute a new variable that states the depth of the active layer in inches. The conversion formula is:

(depth in inches) = (depth in centimetres) / 2.54

What is the mean depth of the active layer, measured in inches?

A small set of data has been collected to explore how much of an effect Thawing
Degree Days (TDD) have on the depth (in cm) of the active soil layer overlying
permafrost. Here is the data that was collected from a sample of six locations. As a
data entry check, the sum of the TDD column should be 10850.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
