In a study on wild bears, researches measured the head lengths and head widths, in inches, of 143 wild bears. The ages of the bears ranged from newborns (0 years) to 15 years. The box plots summarize data from the study. Place the information in the correct table - male or female. Male Bears Had a larger IQR Wide range of head lengths widths Range of head widths was about 6" Median head length was 13.5" Female Bears Had a smaller IQR The head lengths widths were close together Range of head lengths was about 6" 3rd quartile of head length was 13.5" Box Plots & Frequency Graphs (Day 2) (make sure you watch the video completely and answer all the questions!) What do you remember about Box Plots Frequency Tables? Box Plots & Frequency Graphs (Day 2) Based on the video you just watched, see if you remember the answers to these questions... The median score is the middle score, which divides the scores in half. The lowest score was 0, while the highest score was 90. The lower 50% of the scores were from 0 - 23, while the upper half of the scores were from 23 - 90. The interquartile range was from 18-38, and the scores were skewed to the right. The box plot goes with which frequency graph? Frequency Graph A Frequency Graph B Frequency Graph C 50% of the students spent.... between $4 - $20 between $20 - $36 between $24 - $36 between $36 - $40 The quartile which showed the greatest spread was.... 1st 2nd 3rd 4th Match the frequency table A - D to the Box Plot Graph A Box Plot 4 Graph B Box Plot 2 Graph C Box Plot 1 Graph D Box Plot 7 Match Frequency Graph E - H to the Box Plot Graph E Box Plot 5 Graph F Box Plot 8 Graph G Box Plot 6 Graph H Box Plot 3 Looking at Box Plot 6, which quartile shows the biggest spread in test scores? 1st 2nd 3rd 4th Which Box Plot would you describe as skewed to the right? #1 #4 #6 #8 Look at Box Plot 4... would you describe the data as skewed? yes, because all of the data is between 0 - 60 yes, because most of the data is between 0 - 22 no, because most of the data is between 38 - 60 no, because the data is evenly distributed
