IV- Their Diet              DV- Blood Pressure

Step-by-step explanation:

You can always think of your IV as the variable that's gonna "change" and your DV will be "measured". So ask yourself what's being changed, and measured?

Well we can infer that blood pressure is what the researcher is measuring. We know this because his whole goal in the experiment is to see a change.  

And IV we can infer will be what's changing. I believe their diet would be what's changing.

I hope this helps! Try and use the replacement words for the IV and DV, they help a lot!!

Thanks for letting me help!!

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
