Question

the double - bar graph shows the win - loss records for the carolina panthers football team in the years 1995 - 2001.
between which 2 years did the panthers have the greatest change in their win - loss record?
a between 1999 - 2000
b between 2000 - 2001
c between 1998 - 1999
d between 1995 - 1997

Explanation:

Step1: Analyze each time period

• For option A (1999 - 2000): Compare win - loss bars of 1999 and 2000. The change in win and loss counts seems relatively small.
• For option B (1998 - 1999): Compare win - loss bars of 1998 and 1999. The change is not as significant as in some other periods.
• For option C (2000 - 2001): Look at the win - loss bars of 2000 and 2001. The win count drops drastically (from a non - negligible number to almost 0) and the loss count increases significantly.
• For option D (1995 - 1997): The change in win - loss over these two years (comparing 1995, 1996, 1997) is not as large as in 2000 - 2001.

Step2: Determine the greatest change

By visually inspecting the bar graph, the period between 2000 and 2001 shows the most dramatic change in the win - loss record of the Carolina Panthers. The win bar for 2001 is much shorter than for 2000, and the loss bar for 2001 is much longer than for 2000, indicating a large change in the win - loss record.

Answer:

C. Between 2000 - 2001
