Welcome to our Data, Graphing, and Statistics page. Here you will find lots of data handling and analysis worksheets and learning materials to explain the different terms, such as the mean, median, and mode, or how to draw Venn diagrams. The worksheets will help your child to practice handling data, graphing, and calculating statistics to become more confident in handling and interpreting a range of data.
Learning Data, Graphing and Statistics
Learning to read, organize and understand data is a key skill in today’s world. Learning these skills starts in the first grade, and goes through all school years.
In the first grade children learn how bar graphs work by reading and interpreting a range of bar graphs and picture graphs with a scale going up in ones.
In the 2nd grade children read and interpret a range of bar graphs and picture graphs with a scale going up in ones or twos, they can draw missing bars on a bar graph to the correct height and Use the information in a bar graph to add data into a table. In the 2nd grade children are introduced to Venn Diagrams.
At a 3rd grade level, the bar graphs are showing a range of different scales such as 2s, 5s, 10s, 100s. The pictograms are becoming more complex with each symbol representing more than one unit. Children are also introduced to line graphs. The questions are more varied, asking how many more, or how many less, the total of several bars combined. The interpretation of the graph is becoming more difficult than at 2nd grade.
At a 4th grade level, the bar graphs and line graphs are becoming more complex and involve decimals and larger numbers.Venn Diagrams are more complex and include 3 circles. The scales used at 4th grade are varied, and may include decimal scales.The questions are probably at the same sort of level as 3rd grade, but the complexity of the data makes them harder. In statistics children in the 4th grade learn to find the mean of up to 5 numbers, find a missing data point when the mean is given and find the median of a set of data.
At the 5th and 6th grade level graphs are becoming more complex, with more variations of data and scales such as decimals and fractions. Children learn to draw graphs based on data and use operations to solve problems involving information presented in graphs. In statistics children learn to find the mean, find a missing data point when the mean is given, and find the median of a set of data.
