Exam 2 Review: Finance Concepts and Calculations

Exam 2 Review

Chapter 5: Time Value of Money (Practice quizzes, MindTap, and class examples)

Key Concepts

  • Future Value (FV): Represents the value of an investment at a specific future date, considering interest earned.
  • Simple Interest: Interest earned only on the principal amount. FV = PV + PV(I)(N)
  • Compound Interest: Interest earned on both the principal and accumulated interest. FV = PV x (1+I)^n
  • Compounding: The process of converting present values into future values.
  • Discounting: The process of converting

Direct Proof and Counterexample I: Introduction to Proof Techniques

Section 4.1 – Direct Proof and Counterexample I: Introduction

Discovery and Proof

Discovery and proof are integral parts of problem-solving. When you believe a statement is true, try to understand why. Success validates your discovery, while failure provides insights into the problem and may reveal the statement’s falsity.

Assumptions

  • This text assumes familiarity with basic algebra laws (see Appendix A).
  • We utilize the three properties of equality: For all objects A, B, and C, (1) A = A, (2) if A

Histograms

Appropriate for quantitative data

  • X-axis is quantitative
  • Y-axis is the frequency of the data in the bin
  • Bins are a range of values for collecting data, should be the same size

Shape

  • Symmetric/Bell-shaped
  • Normal
  • Skewed
  • Uniform

Center

  • Mean – useful when data are symmetric
  • Median – useful when data are skewed/outliers
  • Mode – useful for categorical data
    • Unimodal
    • Bimodal

Spread

  • Range – easy to calculate, not useful
  • Interquartile range – easy to calculate, useful when data are skewed/outliers
  • Standard

Flexible Budgets & Direct-Cost Variances in Management Control

Chapter 12: Flexible Budgets, Direct-Cost Variances, and Management Control

12-4 What is the key difference between a static budget and a flexible budget?

The key difference is the output level used to set the budget. A static budget is based on the level of output planned at the start of the budget period. A flexible budget is developed using budgeted revenues or cost amounts based on the actual output level in the budget period. The actual level of output is not known until the end of the budget
