You are preparing a case study on the dallas cowboys. you use many methods of data collection in creating the case study. here is an excerpt:

the dallas cowboys were formed in 1960 and have had seven head coaches since then. i surveyed 100 people and one of the questions was, who is your favorite coach of the dallas cowboys? seventy people said tom landry, fifteen said jimmy johnson, five said bill parcells, and ten answered other. one of those who answered other was my brother. i asked him which coach was his favorite and he said, "barry switzer because he was the last one to win a championship." i knew he was kidding because he had a smirk on his face.

the excerpt relays information gathered from questionnaires, interviews, observations, and historical data. identify the information from the case study that was collected by each of the four methods.

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
