2.3 EXERCISES For Extra Help: MyLab Statistics Building Basic Skills and Vocabulary True or False? In Exercises 1-4, determine whether the statement is true or false. If it is false, rewrite it as a true statement. 1. The mean is the measure of central tendency most likely to be affected by an outlier. 2. Some quantitative data sets do not have medians. 3. A data set can have the same mean, median, and mode. 4. When each data class has the same frequency, the distribution is symmetric. Constructing Data Sets In Exercises 5-8, construct the described data set. The entries in the data set cannot all be the same. 5. Median and mode are the same. 6. Mean and mode are the same. 7. Mean is not representative of a typical number in the data set. 8. Mean, median, and mode are the same. Graphical Analysis In Exercises 9-12, determine whether the approximate shape of the distribution in the histogram is symmetric, uniform, skewed left, skewed right, or none of these.
