The line of best fit shoualways be shown on a scatter plot.
What should always be shown on a scatter plot?
Under which circumstances does the mean = median = mode of a sample?
standard error of the mean measures the variability of the raw data
The SE of the mean measures the uncertainty of the estimate of the population mean
SE of the mean measures the uncertainty of the estimate of the sample mean
The SE of the mean depends on the sample size
The SE of the mean can be estimated from several samples of the same population
