Grade 8 - Statistics & Probability

Standard 8.SP.1 - Interpret the data in a histogram to complete a frequency table.

Included Skills:

Analyze the modes of displaying data and the reasonableness of conclusions.
• Investigate and report on the advantages and disadvantages of different types of graphs, including circle graphs, line graphs, bar graphs, double bar graphs, and pictographs (e.g., circle graphs are good for qualitative data such as favourite activities and categories such as money spent on clothes, whereas line graphs are good for quantitative data such as heights and ages
• Engage in a project that involves:
- the collection and organization of first- or second-hand data related to a topic of interest (such as local wildlife counts or surveying of peers)
- representation of the data using a graph
- explanation of type of graph chosen by self and peer
- description of the project, challenges, and conclusions
- self-assessment.
• Suggest alternative ways to represent data from a given situation and explain the choices made.
• Find examples of graphs of data in media and personal experiences and interpret the information in the graphs for personal value.
• Analyze a data graph found in media for features that might bias the interpretation of the graph (such as the size of intervals, the width of bars, and the visual representation) and suggest alterations to remove or downplay the bias.
• Provide examples of misrepresentations of data and data graphs found within different media and explain what types of misinterpretations might result from such displays.
