@mathteacherhal (cont.) Ckpt 2.3, Q10: Would it be safe to assume the scale starts at 0 and goes in intervals of 0.5? #math80

[Maribel Gordon @Galchemy_]

@mathteacherhal Hi -- sorry for all the tweets. On #10 of Checkpoint 2.3 for #math80, there is no num. scale for X-axis (chart). (cont.)-->

[Maribel Gordon @Galchemy_]

@mathteacherhal the median is not, then the median would be a better indicator of center for the distribution?

[Maribel Gordon @Galchemy_]

@mathteacherhal Whoops, thanks for clearing that up. :) So since the mean is affected by outliers in a skewed distribution and (continued)->
