What affects the value of the sample mean? If you took the time to collect data

Question

What affects the value of the sample mean? If you took the time to collect data on epiphytes from five more sycamore trees, what would you expect to happen? What is variance? squared differences between each point and the sample mean ("sum of squares"), standardized to sample size by dividing by the degrees of freedom (n-1). Variance increases as points are farther from the mean value of the sample. What is standard deviation? squareroot of the variance. Because variance incorporates distance^squared, taking the squareroot returns the units of standard deviation to the distance of points from the mean. Like variance, standard deviation increases as points are farther from the mean value of the sample. Which statements are accurate?
