6. Analyze results - Graph the data from Table 4 and describe what your graph looks like (you do not have to submit a picture of the actual graph!).

11) [3.2] In Microsoft Excel (or spreadsheet application of your choice: see above), plot a line graph that shows how the mercury concentration of the five species varies over time. Think about which is the dependent and which is the independent variable. Be sure to label your axes. Copy your completed graph into the space below. (4pts)

#Use scatterplot to determine whether there is any relationship between mother's age and the maternity length

23) Which of the following is observed in a scatter plot when there is an inverse relationship between x and y?

- Graphs show trends or relationships between two variables. They should be numbered and titled.

4) Use exponential regression (or find a constant ratio) to determine an equation for the data.

quickly generate the reports and graphs of long statistical data by using different analysis variable. This helps the user to get the desired outcome in short span of time with less use of computing skills and knowledge which means the user doesn’t have to be a computer genius to get the reports that are necessary for the decision-making.

Repeat step 16 for each level of the independent variable (add 3 pennies, then 6 pennies, then 9 pennies, then 12, and then finally 15 pennies to the

The bar graph was introduced after the picture graph. The information used in the picture graph was transferred to a bar graph to show the students the same information in a different format.

There is no clear relationship between the two variables in the scatter plot. The points are in no specific pattern, suggesting that there is no significant correlation between the variables years and credit balance.

Assume that you are preparing a report on MM207 statistics students at Kaplan University to present to the Kaplan Board of Trustees. Prepare an appropriate graphical representation for each of the following variables.

6. Why is the black line so much more variable than the red line? What 's the difference between the data they show?

To do this, one must identify both the variable and independent variable, and place each one on its correct axis. In college algebra it is mentioned that the independent variable is placed on the x-axis, and the dependent variable is placed on the y-axis. Knowing this information is dire to the accurate visualizations of data; if the independent variable is confused of mistaken as the dependent variable, then the results of the experiment would be false and inaccurate.

The general multiple regression equation is y = a + b1x1 + b2x2 + b3x3 + … + bkxk, where a is the intercept and bk is the coefficient of the independent variable xk.

Explain how regression can be used to analyse the relationship between political freedom and real GDP per capita? -Regression is be used to show whether there is a positive or negative relationship between political freedom and GDP per capita. The coefficient of b determines the slope of the line and how an increase in X affects Y. The regression also determines the R squared which shows how closely the X and Y variable are correlated within the regression. The confidence levels indicate how confident political freedom has an impact on GDP at a particular confidence level. The P value explains whether to accept the null hypothesis or to reject it.
