TMA1 v3. 16 Score: 1/1 Answered Score: 1/1 Answered Score: 2/3 Answered Score: 0/1 Answered Score: \( 2 / 4 \) Answered 5 marks Partially answered 5 marks Calculate the mean to three decimal places 0.553 kg b) Calculate the standard deviation. \( \square \) Round your answer to 3 decimal places.

To calculate the mean, you'll start by adding all your data points together and dividing by the total number of points. If you had values like 0.5, 0.6, and 0.7, you'd sum them to get 1.8, and then divide by 3, giving you a mean of 0.6. Don’t forget to emphasize precision, round your results to three decimal places to maintain accuracy! When it comes to standard deviation, you'll need to determine how far each data point is from the mean. First, calculate the variance by finding the average of the squared differences from the mean. Finally, take the square root of the variance. If, for instance, you find a variance of 0.01, the standard deviation would be \( \sqrt{0.01} = 0.1 \). Remember to round your final answer to three decimal places, just like with the mean!
