"I've seen levels of compliance with the civil rights bill and changes that have been most surprising," King had

The TI84 graphing calculator has the ability to create scatter plots, box and whisker charts, histograms and broken line graphs. This activity will ask the user to enter data into the calculator (or download a file that contains the data), find the important statistical measures, create a box and whisker chart and create histograms. Problem: Creating a Box and Whisker Chart and a Histogram for a set of data Let’s create a box and whisker chart for the age at which Presidents of the United State

Based on the table, how much more will an adult with an Associate degree earn than a person with a high school diploma over the course of a 40 year work career? Is there a greater difference in the median salaries between No high school diploma and High school diploma, or between a high school degree and an Associate degree? If the same student is not a New York State resident, then the cost increases. What is the total cost of a two year degree for a non-New York resident? How long will it t

What does it really take to win a Super Bowl? During this activity you will explore the statistics behind winning and losing the game. make predictions and explain your data. correlation, causation, linear regression

Some questions in algebra and algebra 2 will ask for the equation of a curve or correlation coefficient. The r-value number describes both how well the equation of the curve fits and whether the graph is increasing or decreasing. The r- value will be positive if the graph is increasing and the r-value will be negative if the graph is decreasing. The closer the absolute value of r is to 1, the better the curve fits the data. An r-value of 1 means the curve fits the data perfectly and has a positi

The statistics behind the salaries of the teams and also make some predictions based on those salaries.

Students are given the length and speeds of 9 different animals and then asked to determine the equation of the curve of best fit. Students are then asked to explore whether the equation would fit other animals including humans. Students are asked to identify possible outliers to the data

It is ironic that in this age of recession, baseball players are doing better than they ever have before. Teachers are chastised for asking for full time wages for working 10 months a year, while ballplayers play a game for 6 months a year and the average major league ballplayer is paid FIFTY TIMES (average major league salary $2 million/year … Starting teaching salary $40K) that of a beginning teacher.

Based on the data in the graph below, determine an appropriate growth model for the population of the world. Be careful about the years that you use. Remember 10000 BC could be considered -10000, or you could use 0 for 10000 BC and then adjust the other years appropriately. You should find at least three growth models and then explain which of the models is the most appropriate. Use residuals, graphs and correlation coefficients to explain why your model is the most appropriate. Linear, exp
