Work, Wages, Productivity & Economic Distribution — Practice · Grade 12 Social Studies

Chapter: Measuring the Economy & Public Policy

What this practice covers

By the end of Work, Wages, Productivity & Economic Distribution you should be able to:

8 questions, written answer, each with a worked explanation.

Vocabulary used: compensation, labor productivity, mean, median, wealth.

Problem 1

Why can a higher hourly wage yield a lower weekly gross total?
Answer and explanation

Hours can differ. Multiply the rate by the relevant hours and period, then compare other conditions. The supplied offers yield $200 and $300 respectively, so rate alone cannot rank total income.

Problem 2

What does the supplied productivity increase establish about wages?
Answer and explanation

It establishes no wage change by itself. Output per hour rises 20 percent, while compensation needs separate records. Technology, bargaining, institutions, and distribution can affect how a productivity gain is shared.

Problem 3

Why can mean income exceed median income in the example?
Answer and explanation

The high value of 60 raises the total to 100 and mean to 20, while the middle ordered value remains 10. The statistics summarize different aspects of distribution and do not establish anyone’s wealth.

Problem 4

Why should an access program distinguish applications from placements?
Answer and explanation

They are different stages and outcomes. More applications can show greater participation without establishing additional jobs. Compare selection, vacancies, barriers, and timing to understand how the program’s mechanism operated.

Problem 5

Invented annual incomes in one unit: 10,10,10,10,60. No asset or debt records are supplied. Calculate mean and median and evaluate a claim that everyone is equally wealthy.
Answer and explanation

Mean income is 20 and median income is 10. The values show unequal incomes, while wealth cannot be determined without assets and liabilities at a defined time. The claim confuses an average flow with equal individual stocks. More definitions and records would be needed to compare purchasing power or household circumstances.

Sum and divide by five.

Identify the middle ordered value.

Separate income from wealth.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 6

Does a pay gap alone identify one complete causal explanation?
Answer and explanation

No. It is evidence requiring defined measures and inquiry into hours, roles, treatment, opportunity, and institutions. A careful explanation tests mechanisms without denying the gap or assigning one experience to everyone in a group.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 7

Invented incomes: 5,5,5,5,30. Calculate mean and median and state a wealth limitation.
Answer and explanation

The total is 50, so mean is ten and median five. Assets and debts are absent, so wealth cannot be calculated. Neither average is every person’s income or a complete measure of well-being.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.

Problem 8

Offer A is $18 for ten hours; B $15 for 15. Calculate weekly gross pay and identify a missing comparison.
Answer and explanation

A gives $180 and B $225 before deductions. B’s larger total uses five more paid hours; commute, benefits, stability, time alternatives, and deductions remain missing. Rate and total income are different measures.

Response criteria

  • Explain the relevant institution or economic concept accurately; show correct calculations where needed.
  • Connect supplied evidence and stated assumptions to an explained conclusion.
  • Compare feasible options and their effects on different people without stereotypes.
  • Identify a limitation, tradeoff, uncertainty, or condition that qualifies the conclusion.
