Since the last meeting, each member asked 15 or
20 people the following question: "If a slice of
pizza costs $0.58, what would be a fair price to charge?

Today we'll share our data with the group.

We plan to use the range,
mean,
median,
and mode
to help us understand ALL THAT DATA! |

Peggy
shared first. "I asked 15 people, and used a chart
to keep up with the data. It looks like the range of prices is from $0.70 to $1.00. I can't find the mean, median, or
mode ."

"I also used a graph," replied Susan, "and I ran
into the same mean problem."
So I added up the price of EACH response. Then, I divided this
total value by 15 since I had 15 responses."

"I found the mean
to be $0.78," said Mike.
"Your mean, green machine comes through again!" stated Susan.
"Let's use it to find the mean of your15 data
results."

1. The mean price was $0.79.
2. The median price was $0.80.
3. The mode price was $0.80.

From
this data, we decided that $0.80 would be a fair price to charge!

"Well,
I'm impressed!" said Marie. "Now we have the data to prove that we are
charging a fair price. I'd like to see someone argue with all that data!"

"No one will
argue with you, Marie," said Susan. And with that, the meeting was dismissed.
