Enter one or two data sets into the fields below, and then select one of the Chart My Data buttons.

For individual (univariate) data sets (DataSet1 and/or DataSet2), each value will be numbered sequentially.

For paired (bivariate) data sets, DataSet1 becomes the horizontal (independent) value set and DataSet2 the vertical (dependent) set.

Note: To access GeoGebra's in-built Data Analysis tools, select list data from the spreadsheet (simplest way is to drag across the column headers to select those columns), and then select the Analysis menu as shown - it is the first of the three spreadsheet menus.

Explore the three menus available, and the various options available within these. They offer a couple of more options for you to view and analyse your data sets.

Sample 1: Bar of soap

Do you use up the same amount of the soap in the shower each morning, or does it depend on the size of the bar of soap?

This data was collected by Rex Boggs in Rockhampton, Queensland.

"I had a hypothesis that the daily weight of my bar of soap in my shower wasn't a linear function, the reason being that the tiny little bar of soap at the end of its life seemed to hang around for just about ever. I wanted to throw it out, but I felt I shouldn't do so until it became unusable. And that seemed to take weeks."

Day = {0,1,4,5,6,7,8,9,11,12,17,19,20,21,22}

Weight = {124,121,103,96,90,84,78,71,58,50,27,16,12,8,6}

Sample 2: Kiama Blowhole: Time Between Eruptions

My family lived for many years in the beautiful seaside town of Kiama, on the South Coast of New South Wales. One of the best known features of the town is the Kiama Blowhole, which blows regularly - or at least, semi-regularly.

This data set shows the time (in seconds) between eruptions over an extended period.

Study the data using different representations. Any predictions you could make?

Eruptions = {83,51,87,60,28,95,8,27,15,
10,18,16,29,54,91,8,17,55,10,35,
47,77,36,17,21,36,18,40,10,7,34,
27,28,56,8,25,68,146,89,18,
73,69,9,37,10,82,29,8,60,61,61,18,
169,25,8,26,11,83,11,42,17,14,9,12}
