To find the standard deviation, first calculate the mean of the dataset: (52.1 + 45.5 + 51 + 48.8 + 43.6) / 5 = 48.6. Next, compute the variance by finding the squared differences from the mean, averaging them, and then taking the square root. The standard deviation of the dataset is approximately 3.2 when rounded to the nearest tenth.
