Data Management Unit

In our new unit of Data management, we will be reviewing the differences between a sample and census as well as interpreting data which is biased or reliable.

Curriculum elements that we will be learning:

collect data by conducting a survey with themselves,their environment, issues in their school or community, or content from another subject, and record observations or measurements;

organize into intervals a set of data that is spread over a broad range 

collect and organize categorical, discrete, or continuous primary data and secondary data and display the data in charts, tables, and graphs that have appropriate titles, labels and scales

select and appropriate type of graph to represent a set of data

explain the relationship between a census, a representative sample, sample size, and a population

read, interpret, and draw conclusions from primary data and secondary data

determine, through investigation, the appropriate measure of central tendency (i.e., mean, median, or mode) needed to compare sets of data

demonstrate and understanding of the appropriate uses of bar graphs and histograms by comparing their characteristics

compare two attributes or characteristics by using a scatter plot and determine whether or not the scatter plot suggests a relationship

identify and describe trends, based on the rate of change of data from tables and graphs, using informal language

compare two attributes or characteristics, using a variety of data management tools and strategies

When to use the different graphs
