Estimating the sample mean and standard deviation from the sample size, median, range and/or interquartile range
TL;DR: In this article, the authors proposed a new estimation method by incorporating the sample size and compared the estimators of the sample mean and standard deviation under all three scenarios and presented some suggestions on which scenario is preferred in real-world applications.

Estimating the sample mean and standard deviation from the sample size, median, range and/or interquartile range
TL;DR: This work proposes a new estimation method by incorporating the sample size that greatly improves existing methods and provides a nearly unbiased estimate of the true sample standard deviation for normal data and a slightly biased estimate for skewed data.
