Today we started our last unit:  Unit 6 - Describing Data.  We reviewed the 5 number summary (the values needed in order to make a box and whisker plot).  We also reviewed the range (maximum - minimum), and the interquartile range which is also known as the IQR. Calculate the IQR by taking your Upper Quartile/Q3 and subract the Lower Quartile/Q1 from that.  In other words, IQR = Q3 - Q1.  We completed the guided notes on our statistic vocabulary and practiced identifying the 5 number summary.  We then used the 5 number summary to make a box and whisker plot.  We then compared how the same set of data looks when plotted as a box and whisker plot, a dot plot, a frequency table and a histogram.  Homework is to complete the basketball box and whisker plot worksheet.

Today we started Unit 5 - Geometric and Algebraic Connections.  We reviewed what a midpoint is.  A midpoint is the middle of a line segment.  It divides a line segment into two equal parts.  To calculate a midpoint, you need two coordinate points (x1, y1) & (x2, y2).  You will either be given the two coordinate points, or you will be given a coordinate plane with a line segment.  If you are given a line segment, you will have to determine the coordinate points for the two endpoints.  
To calculate the midpoint,
1) add the two x values & then divide by 2 to get the x-value of the midpoint
2) add the two y values & then divide by 2 to get the y-value of the midpoint
