1,250-word count minimum with three scholarly sources in APA format. My name is Adrienne.

2. The following is a small data set of 25 observations. I want you to calculate some statistics by hand to cement the class material. Excel can be used to solve this problem.Var: 28; 4; 27; 23; 17; 38; 21; 16; 28; 15; 23; 33; 34; 42; 42; 14; 14; 28; 22; 31; 18; 28; 17; 17; 30Create a stem and leaf plot of the data (it is easy to do in Word by making a two column table and entering the numbers in there, bolding the stems).Calculate the following (show your work): Mean, Median, and Mode.

3. Below is the data for infant mortality for 34 OECD countries. The Organization for Economic Co-operation and Development (OECD) is an international economic organization of 34 countries founded in 1961 to stimulate economic progress and world trade. OECD’s website provided some data on infant mortality for 34 countries. Infant mortality (the rate of death of children under 1 year of age per 1,000 live births) is a measure of development. The table below has the data for 34 OECD countries.Create a stem and leaf plot of the data.Calculate the mean, median, and mode for this data.Briefly describe the distribution—focus on the shape of the distribution and whether there are an outliers or strange values. The sum of x Sum(x) for 34 OECD countries is 128.20.

4. Each year the Academy of the Screen Actors Guild gives an award for the best actor and actress in a motion picture. The name and age of each has been recorded since 1996. The data for males and females is given below (the sample size, n =20). The sum of their age is also given.

Construct a stem and leaf plot for each group to compare the distributions. You should use the same scale on both graphs to make a better comparison.Calculate the measures of central tendency for each group. You will need to use the full data from above (use all decimal places to calculate these measures). Use two decimal places for your answers. You can use Excel to help you do this.Calculate the measures of variability for each group (range, variance, standard deviation, CV). You will need to use the full data from above (use all decimal places to calculate these measures). Use two decimal places for your answers. You can use Excel to help you do this.Make a table showing the summary measures for each group. Make a comparison in words summarizing your results.

5. Below is the data for infant mortality for 34 OECD countries. The Organization for Economic Co-operation and Development (OECD) is an international economic organization of 34 countries founded in 1961 to stimulate economic progress and world trade. OECD’s website provided some data on infant mortality for 34 countries. Infant mortality (the rate of death of children under 1 year of age per 1,000 live births) is a measure of development. The table below has the data for 34 OECD countries.Previously, we calculate the mean, median, and mode for this data. Now, add the range, variance, standard deviation, and coefficient of variation for this data.Briefly describe the distribution—focus on the shape of the distribution and whether there are an outliers or strange values. The sum of x [Sum(x)] for 34 OECD countries is 128.20. The Sum(x^2) is 664.42.

6. Todd Andrlik, founder and editor of Journal of the American Revolution, wrote a piece about how young many of the founding fathers were when the Declaration of Independence was first signed in 1776. There were 56 signers of the Declaration of Independence, and their ages are given below, sorted by age.Calculate the measures of central tendency. In addition, calculate the range, variance, standard deviation, and coefficient of variation for this data.The sum of all the values is Sum(x) = 2,479.The sum of the squares of all the values is Sum(x^2) = 116,015.Briefly describe the distribution—focus on the shape of the distribution and whether there are any outliers or strange values.
