Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!

Researchers want to know the offect of captively raising birds on the weight cf the birds. The researchers begin with 100 birds dividad into 2 groups of 50
each. One group of 50 will be raised in captivity and the other 50 are tagged and released into the wid. After 5 yoars, all 100 birds pre collected and
weighed. There are more than 10" different ways to regroup the 100 birds into groups of 50 again, so looking at all the combinations would be too time
consuming to reproduce. In this case, we can run simulations to determine how the original difforence in means compares to those from regrouping the
29
data.
The original groups have a difference of means of 0.27 grams. Researchers run 1,000 simulations regrouping the data into 2 groups at random and record
the differences in means for the groups in each simulation. The histogram shows the differences in means from the simulations.
They determine that the mean of the differences of means from the simulations is 0.0021 grams and the standard doviation for the differences of means
from the simulations is 0.112 grams.
