This article explores how to calculate the mean location of deep-sea jellyfish based on recorded depths in relation to the ocean surface. A marine biologist records six depths: –2278 feet, –1875 feet, –3210 feet, –2755 feet, –2407 feet, and –2901 feet. Using these values, we compute the mean depth, which is found to be –2571.6 feet. Additionally, we provide practice examples to guide readers through the mean calculation process, including temperature data. The method is demonstrated with clear steps for better understanding.

Mean= –2278+(–1875) +(–3210)+(–2755)+ (–2407)+(–2901) = = –2571 6 –15,426 ANSWER 6 The mean location in relation to the ocean surface is –2571 feet. EXAMPLE 1 Finding a Mean Biology A marine biologist records the following locations of 6 deep sea jellyfish in relation to the ocean surface: –2278 feet, –1875 feet, –3210 feet, –2755 feet, –2407 feet, and –2901 feet. What is the mean location of the deep sea jellies?
