Answer:

Meteorologists use computer models to predict the weather. And computational power has come an extended way. Yet meteorologists still have trouble correctly predicting the weather over some days. Sometimes they don’t even comprehend right over 24 hours! Why does this happen? Their ability to predict the weather is restricted by the number of available data, the time available to research it, and therefore the complexity of weather events.

When you are doing an experiment that will have multiple trials, how do you handle averages?

son4ous [18]

The answer is B. The individual trials and the averages should each have their own columns in the data table.

In an experiment, you want to be able to see all of the data, so you should always include the data from each individual trial; however, it's important to have a separate column for averages, so you are able to compare all of the data.

Hope this helps! :)
