Step 1
: Identify the best fit for a line graph based on the given options.

A line graph is best used when showing trends or changes over time, which can be represented by connecting data points with straight lines. This type of graph is particularly useful when there are many data points, and it helps to visualize the general pattern or trend in the data.

Step 2
: Evaluate the given options according to the identified best fit for a line graph.

A. When the values on both axes are numbers - YES, this is a good situation for a line graph as it helps visualize trends and relationships between variables. B. When a grade distribution is displayed - NO, this is not the best situation for a line graph. A bar graph or a histogram would be more appropriate to compare individual grades or grade ranges. C. When showing trends - YES, this is an excellent situation for a line graph as it excels at displaying trends and patterns in the data. D. When representing parts of a whole - NO, this is not the best situation for a line graph. A pie chart or a stacked bar graph would be more appropriate for comparing proportions or parts of a whole.

Final Answer

The best situation to use a line graph is when showing trends (Option C). A line graph is particularly useful when there are many data points, and it helps to visualize the general pattern or trend in the data.

Why is the median​ resistant, but the mean is​ not? Choose the correct answer below. A. The mean is not resistant because when data are​ skewed, there are extreme values in the​ tail, which tend to pull the mean in the direction of the tail. The median is resistant because the median of a variable is the value that lies in the middle of the data when arranged in ascending order and does not depend on the extreme values of the data. B. The mean is not resistant because it is dependent upon the sample​ size, n. The larger n​ is, the smaller the mean becomes.​ However, the median is resistant because it is not dependent on the sample​ size, n. C. The mean is not resistant because when data are​ skewed, there are extreme values in the​ tail, which do not pull the mean in that direction.​ However, the median is pulled in the direction of the extreme​ values, making it resistant. D. The median is​ resistant, while the mean is​ not, because when there are extreme values in the​ tail, the value of the median changes while the mean does not.
