127. A bar chart shows the frequency for the distribution of a qualitative variable. A pie chart shows the relative frequency for the distribution of a qualitative variable. The pie chart is also a great way to make a visual message of the proportions that each variable contributes to the total observations. 128. A frequency distribution shows the number of observations in each class. A cumulative frequency distribution shows the sum of number of observations in a class plus all lower ranked or valued classes. 129. A bar chart shows the frequency distribution of a qualitative variable. A qualitative variable is discrete and not continuous. Therefore, placing a space between each bar reflects the fact that a qualitative variable is not continuous. 130. TRUE 131. FALSE 132. FALSE 133. TRUE 134. TRUE 135. TRUE 136. TRUE 137. TRUE 138.
