5-Number (5#) SummaryThe five-number summary of a distribution consists of the smallest data point, the first quartile, the median, the third quartile, and the largest data point.

Number of Text MessagesFirst we must put the data in order from smallest to largest.

***Sample Size:

#3 MedianThe median is the midpoint of the distribution that has been ordered from smallest to largest, such that half of the data points are smaller and half of the data points are larger.

Notation: _________

#1 MinimumThe minimum is the smallest data point in the data set. Do not exclude any outliers.

Notation: ____________

#5 MaximumThe maximum is the largest data point in the data set. Do not exclude any outliers.

Notation: ____________

#2 Lower QuartileThe median for the first 50% of the ordered set is the lower/first quartile.

Notation: ___________

What does Q1 Mean?_____________of the people in this room sent less than ___________ text messages.

_____________ of the people in this room sent more than __________ text messages.

#4 Upper QuartileThe median for the second 50% of the ordered set is the upper/third quartile.

Notation: ___________

What does Q3 Mean?_____________of the people in this room sent less than ___________ text messages.

_____________ of the people in this room sent more than __________ text messages.

Data DisplayThis is what the quartiles are actually doing with the data set.

Interquartile RangeThe interquartile range is the range of data between the lower quartile and the upper quartile

Notation: __________

Number of Text MessagesFirst we must put the data in order from smallest to largest.

***Sample Size:

#3 MedianThe way we deal with the median in a data set with an ODD sample size is different.

Once we find the median, it cannot be included in another portion (Q1 or Q3).
