Montana Math MT.CORE.DATA.INT.7

MT.CORE.DATA.INT.7 is a cluster heading. These are the individual standards under it.

• MT.CORE.DATA.INT.7.a

  Summarizing categorical data for two categories in two-way frequency tables and visual representations,

• MT.CORE.DATA.INT.7.b

  Interpreting relative frequencies for categorical data in context, and

• MT.CORE.DATA.INT.7.c

  Identifying possible associations and trends in categorical data.

01

What Students Need to Do

Students count events by type and by weekday or weekend, then put the counts in a two-way table and bar chart. They compare weekend rates by event type and describe any pattern they see.

02

What Mastery Looks Like

A student fills in the table and labels a bar chart correctly. They use the total for each event type to find weekend percentages, then describe a possible association without claiming one category causes the other.

03

Common Misconceptions

Students may divide a weekend count by the total number of events instead of the total for that event type. They may also treat a larger count as a higher rate.

04

How to Assess It

Exit ticket, using made-up Montana tribal college calendar data: 4 of 10 language or arts events and 2 of 10 other events occur on weekends. Make a two-way table, compare the weekend rates, and say whether the data suggest an association.

1. 01

   Print 12 public event notices from a Montana tribal college and local library; students sort by weekday or weekend and language or arts or other, then tally.

2. 02

   Ask: Among language or arts events, what share fall on weekends? How does that compare with other events, and what can this sample not tell us?

3. 03

   Give pairs a completed event table; have them draw segmented bar charts, swap papers, and check each other's percentages.

4. 04

   Draft a note for a local library and tribal college comparing weekend rates before they plan a joint language or arts event.
