What is the best way for Mr. Schmidt to ensure all students have a calculator during the statistics unit test?

Providing advance notice for students to bring calculators and ensuring that devices are available for those who do not have one is the most effective strategy for Mr. Schmidt to guarantee that all students have a calculator for the statistics unit test. This approach ensures preparedness and accessibility for every student, accommodating those who may not have had the opportunity or means to acquire a personal calculator.

By giving advance notice, students are informed well ahead of time, allowing them to plan accordingly and bring their own calculators if they have them. At the same time, Mr. Schmidt’s provision of calculators for those who might not own one promotes inclusivity and creates a fair testing environment where all students have equal access to the necessary tools. This strategy minimizes the risk of unpreparedness and fosters an equitable assessment atmosphere during the test.

The other options, while they might suggest alternatives for calculator access, do not guarantee that every student will have a calculator. For instance, requiring students to rely on their own devices or borrowing from friends introduces uncertainty and does not ensure that everyone will be adequately equipped for the test. Sharing calculators could lead to logistical issues, such as time constraints or distractions during the test, which can further hinder performance.
