The mean, standard deviation, and variance are measures of central tendency and dispersion that are commonly used to summarize a data set. The mean is the average value of the data set, calculated by adding all the values and dividing by the number of values. The standard deviation is a measure of how spread out the data is from the mean, calculated by taking the square root of the variance. The variance is the average of the squared differences between each value and the mean. For the data set 9,29,46,27,46,15,10,44,19,33,38,7,34,28,8, the mean is 26.2. However, the standard deviation and variance provided in your message seem to be incorrect. The correct standard deviation is approximately 14.07 and the variance is approximately 197.96.
