# TVO Learn 7 & 8 Data

What is the probability of drawing a pencil from the bag containing 6 items?

OVERALL EXPECTATION

D1. manage, analyse, and use data to make convincing arguments and informed decisions, in various contexts drawn from real life.

D1.1 explain why percentages are used to represent the distribution of a variable for a population or sample in large sets of data, and provide examples

D1.2 collect qualitative data and discrete and continuous quantitative data to answer questions of interest, and organize the sets of data as appropriate, including using percentages

D1.3 select from among a variety of graphs, including circle graphs, the type of graph best suited to represent various sets of data; display the data in the graphs with proper sources, titles, and labels, and appropriate scales; and justify their choice of graphs

D1.4 create an infographic about a data set, representing the data in appropriate ways, including in tables and circle graphs, and incorporating any other relevant information that helps to tell a story about the data

D1.5 determine the impact of adding or removing data from a data set on a measure of central tendency, and describe how these changes alter the shape and distribution of the data

D1.6 analyse different sets of data presented in various ways, including in circle graphs and in misleading graphs, by asking and answering questions about the data, challenging preconceived notions, and drawing conclusions, then make convincing arguments and informed decisions
D1.1 identify situations involving one-variable data and situations involving two variable data, and explain when each type of data is needed

D1.2 collect continuous data to answer questions of interest involving two variables, and organize the data sets as appropriate in a table of values

D1.3 select from among a variety of graphs, including scatter plots, the type of graph best suited to represent various sets of data; display the data in the graphs with proper sources, titles, and labels, and appropriate scales; and justify their choice of graphs

D1.4 create an infographic about a data set, representing the data in appropriate ways, including in tables and scatter plots, and incorporating any other relevant information that helps to tell a story about the data

D1.5 use mathematical language, including the terms “strong”, “weak”, “none”, “positive”, and “negative”, to describe the relationship between two variables for various data sets with and without outliers

D1.6 analyse different sets of data presented in various ways, including in scatter plots and in misleading graphs, by asking and answering questions about the data, challenging preconceived notions, and drawing conclusions, then make convincing arguments and informed decisions

OVERALL EXPECTATION

D2. describe the likelihood that events will happen, and use that information to make predictions

D2.1 describe the difference between independent and dependent events, and explain how their probabilities differ, providing examples

D2.2 determine and compare the theoretical and experimental probabilities of two independent events happening and of two dependent events happening
D2.1 solve various problems that involve probability, using appropriate tools and strategies, including Venn and tree diagrams

D2.2 determine and compare the theoretical and experimental probabilities of multiple independent events happening and of multiple dependent events happening

## Most Suitable Graph

Learn how to choose the best type of graph to represent different data sets with Teacher Kristina.
Explore how to display data in appropriate graphs using specific conventions and you'll explain and justify responses to questions using the data in the graphs you create.
This video activity highlights expectations D1.3, D1.4, D 1.5 and D1.6. For additional learning activities for grade 7 data, please explore the TVO Learn activities listed below.
