Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

1. Graph the values on a scatter plot, where year is the x-vale and record time (in seconds) is
the y-value. Label both axes.
2. Discuss the following in paragraph form: Does the scatter plot show a positive
correlation, negative correlation, or no correlation? Does the correlation appear to be
linear, quadratic, or exponential? How do you enter the data set in the calculator? After
entering the data, how do you find the equation for the line of best fit? Give an example
of interpolation for the data set and show how you would calculate the record time. Give
an example of extrapolation for the data set and show how you would calculate the record
time. How would introducing a new data point (year 1982, record time 8 seconds) affect
your line of best fit?
