Question

choose the best tool for each scenario. identifying a trend in temperature change over time: graph measuring the mass of a product of a chemical reaction: graduated cylinder calculating a best - fit line for a data set: nongraphing calculator stopwatch computer done

Explanation:

A computer is the best tool for calculating a best - fit line for a data set. Computers have software (such as spreadsheet software like Excel, statistical software like R or SPSS) that can perform complex calculations (using algorithms like least - squares regression) to determine the best - fit line for a given data set. A nongraphing calculator is mainly for basic arithmetic and some simple statistical calculations (like mean, standard deviation), but not as efficient or powerful for fitting a line to a data set. A stopwatch is used for measuring time intervals.
