Here you will find five different graphs and charts for you to consider. Not sure about which graph to use? Confused between bar graphs and pie charts?

In this unit students develop a variety of mathematical skills including: * Data collection and organisation, using a questionnaire about grocery stores, brand names and cell-phones.* Graphical representation of the data collected using bar graphs and pie charts.* Understanding cumulative data, as well as developing and interpreting frequency tables. * Analysis of data to answer questions, using graphs and tables.* Reading and interpreting fi gures, in the context of a newspaper report concerning skills development. * Calculating the various measures of central tendency and percentages in the context of workers and wages.* Working with range and spread of data.* Identifying distortion and manipulation of information.* Identifying patterns and trends,  through working with scatterplots and broken line graphs.* Making simple predictions and comparisons.

Drawing graphs of real life situations Drawing and interpreting more than one graph on a system of axes. Grids, maps, compass Use and interpret scale drawings, build scale models Compare, summarise and display data - describe trends Probability and misuse of statistics in society

This tool creates visualizations graphs of the data your twitter/hashtag archives. Use it to help you understand trends such as the number of Tweets over time, top users and words, sentiment, and more.

Great resoruces. Maybe we can change it for South African cricket scores?

Mathematics is used in interesting, and often less than accurate, ways. Newspapers present graphs showing apparently correlated variables, but with a little thought, some of the time you will find that whilst it looks like two variables are connected, there is actually no cause and effect. Sometimes this is because there is a third factor causing the movements in the variables - for example, if it is hot and sunny, sales of sunscreen lotion increase, as do sales of air-conditioners. If you plot these sales against each other, you find a correlation. However, they are only connected because of a third variable, the summer weather. Of course, an unscrupulous media can draw connections where they don't exist for more political ends, such as blaming an increase in crime on the sales of hooded sweatshirts. And politicians have been known to confuse cause and effect, thinking that a local crime increase is due to the increased police presence, rather than the other way around.

In this activity, students conduct an investigation to determine the rate of change in the popping of microwave popcorn. Four volunteers will estimate the time in the popping process where the rate of change is at 5 chosen levels. Other students will collect data on number of pops during consecutive 5 second time periods and draw histograms. Students will understand the approximate normal curve for a real data set and the relationship between the rate of popping and the shape of the distribution. This activity also provides an opportunity for students to understand human errors in data collection because not everyone will have the same number of frequencies in the corresponding classes of their histograms.

Really cute assignment from Jeannee

Thanx carolyn.

This could be a great tool to use with students in the clasrrom. They can research their won dataset and visualise it.
