The student will construct and interpret histograms an box plots. Given: Sixty-five randomly selected car salespersons were asked the number of cars they generally sell in one week. Fourteen people answered that they generally sell three cars; nineteen generally sell four cars; twelve generally sell five cars; nine generally sell six cars; eleven generally sell seven cars. Complete the Table Complete the table below using the data provided. Data Value (# cars)FrequencyRelative FrequencyCumulative Relative Frequency Discussion Questions Exercise 1 What does the frequency column sum to? Why? Exercise 2 What does the relative frequency column sum to? Why? Exercise 3 What is the difference between relative frequency and frequency for each data value? Exercise 4 What is the difference between cumulative relative frequency and relative frequency for each data value? Enter Data Enter your data into your calculator or computer. Construct a Histogram Determine appropriate minimum and maximum x and y values and scaling. Sketch the histogram below. Label the horizontal and vertical axes with words. Include numerical scaling.  Data Statistics Calculate the following values: Exercise 5 Sample Mean = EMBED Equation  Exercise 6 Sample standard deviatons = sx = Exercise 7 Sample size = n = Calculations Use the table in section 2.11.13 to calculate the following values: Exercise 8 Median = Exercise 9 Mode = Exercise 10 First quartile = Exercise 11 Second quartile = median = 50th percentile = Exercise 12 Third quartile Exercise 13 Interquartile range (IQR) = _______ - _______ = ________ Exercise 14 10th percentile = Exercise 15 70th percentile = Exercise 16 Find the value that is 3 standard deviations: Above the mean Below the mean Box Plot Construct a box plot below. Use a ruler to measure and scale accurately. Interpretation Looking at your box plot, does it appear that the data are concentrated together, spread out evenly, or concentrated in some areas, but not in others? How can you tell?  !"#%?@A  # $ οΣ}wldVC%hbIThp0J5:@CJ\aJh0JCJOJQJaJh0dOJQJh0dh0dOJQJ hpCJhbITh0JOJQJaJhqhq0JOJQJh0d0JOJQJh0dh0d0JOJQJhbIThp0JOJQJaJhbIThq0JOJQJaJhq0JCJOJQJaJhqhp0Jh,Ph0d0J hp0J h0J h0d0J#$%@A $ V j t $$Ifa$gdAkUl gdq gdpgd0d gd$a$gdq$ U V     Q S [ \ ] ^ ĻxrkakrkakrkXkh>h>0JhAkUh>0J5 h>0J5 h>0Jhq0JCJOJQJhAkU0JCJOJQJhq0JCJaJhDhAkU0J'huo hAkUB*phhuo hAkU5B*phhDh0d0J'huo h0d5B*phhAkUh0d5%hAkUhD0J5:@OJQJ\%hAkUhq0J5:@OJQJ\ rrrr$$Ifa$gdx2l wkd$$If4\ &) " /$64 af4 rrrr$$Ifa$gdx2l wkd$$If4p\ &) " /$64 af4 rrrr$$Ifa$gdx2l wkd$$If4p\ &) " /$64 af4 rrrr$$Ifa$gdx2l wkd$$If4p\ &) " /$64 af4 rrrr$$Ifa$gdx2l wkd$$If4p\ &) " /$64 af4 rrrr$$Ifa$gdx2l wkdd$$If4p\ &) " /$64 af4    R S ^ ~yyyyyyyyl ^`gd>gd>gdqgdqwkdB$$If4p\ &) " /$64 af4 ^  ' ( ) 3 4 f g h ~ . / 1 A a b l ³j[KGA h~0Jh~hAkUhAkU0J:OJQJ\hAkU0J:CJOJQJ\+j hN'hAkU0J:CJOJQJU\hAkU0JOJQJh>0J5OJQJhAkU0J5OJQJ h>hAkUhAkU0JCJOJQJhAkUhAkU0JCJOJQJh>0JCJOJQJ h>0J5h>h>0JhAkUh>0J5 h>0J hAkU0J5hAkUhAkU0J5 ( ) 4 f g h ~ . 0 1 A a b m gd> ^`gd~$a$gd>gd>gdq ^`gd>l m { | 3=>IST\ghz¼rnnnnnfnnh>h>H*h>hD0JCJOJQJaJh>0JCJOJQJaJh~0JCJOJQJaJh>EHOJQJ h=oEHh=oh=oEH h=oh=o h~0Jh~j h>h=oUj5 h>h=oU h>h=ojh>h=oU h>hAkUh>h~0J( 23>HIT[\hyz&gdx2 ^`gd~gd>gd>%&(*:EFHJZefh>0J5:@\h>h>0J5:@\hx20JOJQJh>0JOJQJh>B*phh~h>h>H*h>h~0J h~0JhqB*ph h>h>h>&9:FYZf ^`gd>gd>gdx2 & F gd~gd~ ^`gd~gd>21h:pt/ =!"#$% $$If!vh5)55 5" #v)#v#v #v" :V 4/$65)55 5" / / / / 44 af4$$If!vh5)55 5" #v)#v#v #v" :V 4p/$65)55 5" / /  / / / 44 af4$$If!vh5)55 5" #v)#v#v #v" :V 4p/$65)55 5" / / /  / 44 af4$$If!vh5)55 5" #v)#v#v #v" :V 4p/$65)55 5" / / /  / 44 af4$$If!vh5)55 5" #v)#v#v #v" :V 4p/$65)55 5" / / /  / 44 af4$$If!vh5)55 5" #v)#v#v #v" :V 4p/$65)55 5" / / /  / 44 af4$$If!vh5)55 5" #v)#v#v #v" :V 4p/$65)55 5" / / /  / 44 af4Dd 0  # Abj2Vl;CLFdn>2Vl;CLPNG  IHDR5~+7sRGBIDATx^QJAPy@}/? $\}YK@]'Ͼ# w s׽wd.}wy>,%].gߑ};p>wݻO@}G{ ]u>}YK@]'Ͼ# w s׽wd.}wy>,%].gߑ};p>wݻO@}G{ ]u>}YK@]'Ͼ# w s׽wd.}wy>,%].gߑ};p>wݻO@}G{ ]u>}YK@]'Ͼ# w s׽wd.}wy>,%].gߑ};p>wݻO@}G{ ]u>}YK@]'Ͼ# w s׽wd.}wy>,%].gߑ};p>wݻO@}G{ ]u>}YK@]'Ͼ# w s׽wd.}wy>,%].gߑ};p>wݻO@}G{ ]u>}YK@]'Ͼ# w s׽wd.}wy>,%].x[O {y8%SG}ceN G@zS<%{=^F>O {y8%SG}ceN GKQ3nIENDB`Dd <  C A2 oS{uCjR `! oS{uCjHx=1 @ELL4$`@-V ;o\ łQ!Mgo< It`f>!skgH,řP_)SDž|'P`k#O> F Char Char4CJOJPJQJLC@L  Body Text Indenth^h`>O!> F Char Char3CJOJPJQJnR@2n FBody Text Indent 28d^8`CJOJPJQJaJ>OA> F Char Char2CJOJPJQJnS@Rn FBody Text Indent 38d^8`CJOJPJQJaJ>Oa> F Char Char1CJOJPJQJ6U@q6 F Hyperlink >*B*ph:O:   Book Title 5:@\^>@^  Title $ 5$7$8$9DH$a$5CJ KHOJQJ\aJ NON  Char Char"5CJ KHOJPJQJ\^JaJ JOJ  Exercise NumberCJOJQJaJFOF  Exercise text d\$CJaJPO"P Exercise Number CharCJOJQJaJdOd !
