MTEL Business: Probability and Statistics Chapter Objectives
The Massachusetts Tests for Educator Licensure (MTEL) exams are used to assess compliance with teacher licensing regulations; the Business exam measures student knowledge of various business topics. This Probability and Statistics chapter of the study guide covers topics found in the accounting and quantitative analysis portion of the MTEL exam, which constitutes about 16% of the computer-administered test. The lessons in this chapter include business-related probability and statistics subject matter that you'll encounter on the exam. In its entirety, the assessment includes 100 multiple-choice and two open-response questions.
1. Mean, Median, Mode & Range
The four most common measures of central tendency are the mean, median, mode, and range. Understand and calculate the mean, median, mode, and range through the given sample problems.
2. Calculating the Standard Deviation
Standard deviation helps determine if a set of data is normally distributed by measuring how closely the data set surrounds the mean, or average. Learn about standard deviation, including the steps to calculate it. Explore variance, review examples of calculations, and understand what standard deviation means in regard to a data set.
3. Probability of Simple, Compound and Complementary Events
Probability can be calculated for simple, compound, and complementary events. Explore each type of event, understand how each event differs from the other types, and learn how to calculate each type of event's probability by reviewing examples.
4. Probability of Independent and Dependent Events
Probability is a ratio that predicts the likelihood an event will occur. Explore the concept of probability and understand the difference between independent and dependent events. Learn how to calculate the probability of both independent and dependent events, and review examples.
5. Statistical Significance: Definition & Calculation
Statistical significance is a critical measure to determine the validity of hypotheses in research surveys. Explore the definition of statistical significance, understand its importance, and learn how to calculate and use the p-value.
6. Expected Value in Probability: Definition & Formula
An expected value is the average winning percentage that is likely to be established after many rounds of a game of chance. Learn more about the definition and the formula for the expected value in a gambling casino, and explore an example of how to determine the probability in each event or round.
7. Normal Distribution & Shifts in the Mean
Normal distribution on a graph looks like the outline of a bell, which is why it is described as a bell curve. Learn more about normal distribution and the definitions of shifts in the mean and standard deviations and how to identify them on a graph.
8. Identifying & Calculating Averages
An average is a specified value while a weighted average is the average of a group of numbers with repeated numbers. Learn more about identifying and calculating averages and their formulas.
9. Finding Percentiles in a Data Set: Formula & Examples
Percentiles are a measure that compares individual scores of performance against a data set, in ranges of 0-100. Learn the calculation method of this type of ranking through examples of the formula.
