With their dad's help, ray, joren, and andrew were able to make a histogram and a frequency table.

"gosh, what does that mean dad?" asked ray, joren, and andrew. "well kids," he explained, "it's a way of expressing data in a graphic way, so you can see it." he took them on his knee to explain further. "also, you can know the mean, or average, of all the numbers, the median, or middle, and mode, the number that happened more often."

'wow!" said ray, joren, and andrew. "i bet we could have all sorts of fun with this! Is there anything esle we could make?"

"Of course, kids."
