we can state that the value of the population mean 𝝁 is constant. However, the value of the sample mean 𝑥᪄ varies from sample to sample.

A major shortcoming of the ......... as a measure of central tendency is that it is very sensitive to outliers (جت في الامتحان)

The mean is always the best measure of central tendency because it is heavily influenced by outliers

is the value of the middle term in a data set that has been ranked in increasing order.

The single middle value if 𝑛 is .......... The average of the middle two values if 𝑛 is ..........

The mode is the value that occurs with the highest frequency in a data set

The mean is a better measure when a data set includes outliers.

The mean has the advantage that its calculation includes each value of the data set.

A time-series plot can be constructed by thinking of the data set as a Trivariate data set

if mean > median, then ..................

if median > mean, then ..................

mean = 8 median = 5 mode = 3 (جت في الامتحان)

A survey that includes every member of the population is called a sample.

Random sample, some members of the population may not have any chance of being selected in the sample.
