Can someone check my work for these true/false questions?

If you disagree, can you tell me why? Thanks.





The median is a member of the original set of data.


False





Each set of data has only one mode.


False





Circle graphs are useful for show trends but less useful for comparing parts of a whole.


False





It is possible for the mean to be less than the median.


True





Line graph is good for picturing trends and comparisons of several quantities simultaneously.


True





If the categories represent discrete values, then a histogram should be used; If the categories represent numbers that are continuous and could be regrouped in different intervals, then a bar graph should be used.


False





Scatterplot is good for picturing ordered pairs, correlations, and trends.

I'm not sure about all of them, but your answers one, two, and four are correct. For the first one, the median *can be* a member of the original set of data, but it doesn't have to be (if the original set of data has an even number of members); so false is correct.





If a circle graph is the same as a pie chart (and I believe it is), then your answer to question three is correct.
