Handout

 

Given the data set:

PERIOD 5:{36, 34,26,16,30,45,36,40,32,25,30, 30, 34, 26, 42, 27, 28, 29, 20, 28, 34, 30, 37, 24, 34, 30, 36, 40, 36, 20}

PERIOD 6:

{39,42,30,26,36,30,36,33,28,32,32,27.5,42,18,28,27,34,35,35,26,30,25,33.3,55,30,24,62,4,40,33,42}

1) calculate mean median and mode.

2) multiply each number by 2.54, then calculate the mean, median and mode of the new data set

3) add 3 to each number in the original distribution and again calculate mean median and mode.

Finish handout "Review for quiz".

Also review how to calculate the measures of center: mean, median, mode, midrange and n% trimmed mean.

Complete handout (answer the last two questions in the back of the paper)

Describe the histograms in the handout you received today (except histogram of the ages of your class).

Complete the handout "Measures of Center"

Using the data that we collected in class, draw two histograms, one using 7 bins (5th period) and 8 bins( 6th period) and the other using 5bins (both periods). Then describe each histogram (S.O.C.S.). (Due at the beginning of period)

Continue working on handout (due at the end of period)

p. 18 # 1-3 (explain your answer), 4 and 5(a,b,c,d,e)

Due by end of the period: complete project "AP Survey" (to be done in class)

Brief Reflection: Which of the three types of graphs (Bar Graph, Pie Chart, Rose Diagram) do you think is more "useful" for this project? Explain.

Complete handout (Rose Diagram)

1) p.64 #1 +

 

2)Finish the exercise we started in class. Draw a bar graph and two pie charts: one using the hundredth disks and the other using degrees. Don't forget to be neat and follow all directions.

p. 49 # 4 + finish handout

Complete handout (front page)

Describe the distributions on handout (meals per day) and on page 41 of the textbook. Describe Shape, Outliers, Center and Spread and put it in the context of the problem.

Draw a HISTOGRAM and complete the OGIVE for the data we collected in class
