Farm Data Detectives

"We have a case to crack," said Suzy. "The farmer wants to know which paddock needs the most water."

Little Thunder put on his detective face. "Let's find clues!"

First they checked the rain gauge. "Five millimetres this week," said Spike.

Next they counted the cows in each paddock. They made a tally. One, two, three, four, and a line across for five.

"The top paddock has eight cows," said Suzy. "The creek paddock has four."

Little Thunder drew a bar graph. The top paddock bar was twice as tall.

"More cows drink more water," said Spike.

Then Tokyo the cow showed them a different graph. Its bars looked very strange.

"This graph is tricky," said Suzy. "The numbers don't start at zero. It makes small things look big."

"A misleading graph!" said Little Thunder.

They looked at all their clues together.

"The top paddock needs the most water," said Little Thunder. "We have the evidence!"

"Case closed," said Spike.
