he annual pay salaries for managers at two companies are listed below. • Company A: $32,000, $35,000, $40,200, $44,500, S76,700 • Company B: $36,500, $37,000, $41,750, $42,800, $45,000 siven the distribution salaries, explain which measure of central tendency, the mean or the median, is best suited for comparing salaries across the companies. Use the mean and median values for each distribution to support your answer.

Explain what a box and whisker plot is and how we use it to understand central tendency and variability.

1. Provide an example of a data set whose histogram you would expect to be skewed to the left. Explain why you would expect the histogram to be skewed left. 2. A report on US annual income states both the mean and the median. Which measure of center do you think is larger, the mean or the median? Which would better represent US annual income? Explain.

Identify an important reason for grouping data.

For the project, you will have to: Collect and organize a sample of 30 items of data from a source you find relevant. Some examples: Sports (top HR hitters, rushing leaders, point scorers, etc.) Weather (average daily temperature for a month, max hurricane wind speed, etc.) Business (top-grossing movies, highest-paid athletes, record sales, etc.) Demographics (age, height, weight, etc.) Find the mean, median, mode, and mid-range for your date. Find the variance, standard deviation, and range for your data. Find the five-number summary and determine (mathematically) if there are any outliers. Construct a 95% confidence interval for the mean of your data.       You are allowed to use the calculator for the calculations but you must provide me with the 30 data values you obtain in a neat, organized manner, preferably in a spreadsheet. Also, be sure to provide the source of your data. When you provide the answers to the questions above please use the correct symbols and notation.…

If a data set has an even number of observations, the median

Help please!!    The Fortune Global 500 , also known as the Global 500 , is an annual ranking of the top 500 corporations worldwide as measured by revenue. In total, the Global 500 generated $31.2 trillion in revenues in 2014. The table provides a list of the 30 companies with the highest revenues (in billions of dollars) in 2014. A stemplot or histogram shows that the distribution is strongly skewed to the right.

Does the mean represent the center of the data?

Summarize the effect different kinds of outliers can have on a data set in terms of how we interpret whether we have a good model or not.

Why Mode value is one of the given set of data values?
