True or False 1 point each) (Correct the ones that are false, carn an extra credit point for each.) The statistical method appropriate for summarizing data depends on whether the data are categorical or quantitative. Whenever a dataset contains extreme values, the mean is preferred over the median as a mcasure ot central location. 1. 2. 3. The recommended number of classes for a frequency distribution is 8. 4. A ste and leaf display can show rank order and shape...

1. (2 points). (True False) The median is very sensitive to extreme data points. 2. (2 points). (True False) The t-distribution approaches the standard normal distribution as sample size increases. What type of data (attribute, discrete numerical, continuous numerical) is each of the following variables: 3. (2 points) _____________________ Your gender 4. (2 points) _____________________ Your height Which type of data (nominal, ordinal, interval, ratio) is each of the following variables? 5.

Hey, please do only cluster sampling. I do not understand it. Just give me the 25 nations, and I will run the analysis. Comparing Sampling Methods + There are two main categories of sampling: non-random and random sampling. This mixed grill focuses on random sampling. Quantitative researchers are really interested in the population parameters (that is, the data at the population level). But most of the time, it is simply not practical from a cost and a time consideration to...
