A teacher asks her students to find the average mass of a chicken egg. Each student is provided a carton of a dozen eggs and is asked to create his or her own procedure for finding the average mass. Felicia chooses an egg that appears to be of average size. She places the egg on a balance and records its mass as the average. Darren finds the individual mass of one of his eggs and records it. He repeats the procedure for each of the 12 eggs. He lists all of the masses in order from smallest to largest and then records the most commonly appearing mass as the average. Colin finds the individual masses of all of his eggs. He also asks his classmates for the individual masses of their eggs. He adds the masses of all of the eggs in the classroom and divides by the total number of eggs measured. He records this mass as the average. Ella places all 12 of her eggs on a balance at the same time. She divides the total mass by twelve and records it as the average. Whose procedure is likely to produce the most accurate result?

If you have all the eggs weighed at different times and then write them down, after that add all of the number together. Divide the number by the amount of eggs. BOOM ANSWER!

Answer:

Collin's procedure will likely produce the most accurate result

Step-by-step explanation:

The number of trials done in any lab or scientific investigation helps to reduce the uncertainty in the result or divide the uncertainty proportionally.

Here, Darren among all the students has taken 12 trials for 12 eggs individually while Felicia just picked one egg of average size based on her guess analysis. Collin on the other hand sum up the individual masses of all eggs in the classroom and then takes the average of it. Ella put all 12 eggs at once , finds a combined weight of them and then divides it by 12.

Now, since Collin has taken the maximum number of samples (as he has taken weight of individual eggs of all his class mates), therefore his result will give more accurate result.
