Independent & Dependent Variables
During these two weeks we've really enjoyed our time in math class. We've learned how to use valuable programs such as
, and how to further use our new TI-84 calculators. We also learned how to connect scatter plots and logarithms to the real world through real-life data sets.

A logarithm is the exponent to which the base must be raised to produce that number.
10^x = 1000
The linear regression/line of best fit is the line that best fits the correlation of the data set.

Logarithms are used when you have a large variety of numbers in a graph. You can use the logarithm to make the scale of the graph closer together and the graph easier to read.
log (100,000)= 5
A scatter plot is a graph of plotted points that compare two data sets
There are 3 types of correlations for scatterplots: positive, negative, and no correlation
The easiest way to find the most accurate line of best fit is to use the TI-84 calculator or the
The independent variable also known as x is the value located on the horizontal axis. The independent variable is the input or causes.
The dependent variable or y is located on the vertical axis. The dependent variable is the output or effects.
y depends on x
