Define pooled data versus pooled data with 2 examples. For non-grouped data with 2 examples calculate: arithmetic average median fashion mean square harmonic mean geometric mean

Which of the following are effect measures for continuous data?  a. Mean difference  b. Standardized mean difference

Mean is advantageous than the median because a. It is not influenced by extreme values b. Data needs to be sorted out c. It does not consider all values d. It considers all values in a data

Can you find a set of data such that the mean, median, and variance are all equal to each other? Find as many data sets as possible. If none are possible, explain why. If many are possible explain why. If you find any patterns explain what they are and how they are useful in the hunt for understanding this question.

IQR and outliers

Identify an important reason for grouping data.

How can graphics and/or statistics be used to misrepresent 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.…
