Rosa works at a gelato shop and observes that the number of people buying gelato varies greatly from day to day. for a couple of weeks, she has recorded the number of people at the shop each day, as well as the daily temperature, and has observed a positive relationship between temperature and the number of customers. based on her observations, rosa should multiple choice conclude definitively that people buy more gelato when the temperature rises. determine if there are other relevant factors and attempt to hold these constant before drawing conclusions. continue to gather data on the number of visitors and daily temperatures, because eventually other relevant variables will not matter. throw out the data if it does not show a perfect relationship between buying habits and temperature.

I think the the purchase of Gelato depends a lot on the temperature. A lot of people just want to have something cold, when it is hot outside, for example: Icecream, a cold drink. Although, i don't think it is only related to temperature. Temperature plays a big part in it, but some people might just want ice cream for example on a cold day. lets say there is a girl that just got dumped by her boyfriend, the clichĂ© is that this girl will eat her hurt feeling away with ice cream, no matter what the temperature is. i myself like to enjoy gelato also in winter. I do have to state though, that it is LESS than in summer, but the craving is still there.
