Last updated Dec 7, 2022 Edit

# Extrapolation

Uses trends from historical data to forecast the future.

# Moving averages

A moving average takes a data series and “smoothes” the fluctuations in data to show an average. The aim is to take out the extremes of data from period to period.

Extrapolation is not just drawing a straight line and assuming that conditions will all remain stable or equivalent to historial data. It requires attention to be paid to the various different internal and exterenal factors.

Factors include:

# Pros and Cons of Extrapolation

# Pros

# Cons

# Correlation

Correlation is the strength of the relationship between two variables.

# Independent Variable

The factor that causes the dependent variable to change.

X axis

# Dependent Variable

The variable that is influenced by the indepedent variable. Y axis

# Types of correlation

# Positive correlation

A positive relatioshiop, when the independent increases so does the dependent.

# Negative correlation

A negative relationship, when the independent decreases so does the dependent.

# No correlation

There is no obvious relationship between the two variables.

Strong correlations are very definite, whereas a weak correlation means the data is quite spread.
