1. Calculating the Standard Deviation
In this lesson, we will examine the meaning and process of calculating the standard deviation of a data set. Standard deviation can help to determine if the data set is a normal distribution.
2. Expected Value in Probability: Definition & Formula
After watching this video lesson, you will understand what expected value means. You will learn how to use this value to decide whether a certain action is worth taking or not.
3. Finding Percentiles in a Data Set: Formula & Examples
Percentiles are often used in academics to compare student scores. Finding percentiles in a data set can be a useful way to organize and compare numbers in a data set.
4. How to Calculate Mean, Median, Mode & Range
Measures of central tendency can provide valuable information about a set of data. In this lesson, explore how to calculate the mean, median, mode and range of any given data set.
5. Identifying & Calculating Averages
After watching this video lesson, you will be able to calculate any kind of average, even the average of certain events when some events repeat. Learn the general formula to use to calculate any average.
6. Normal Distribution & Shifts in the Mean
In this video lesson, you will see what a normal distribution looks like and you will learn about the mean of a normal distribution. You will also see what happens when the mean is shifted.
7. Probability of Independent and Dependent Events
Sometimes probabilities need to be calculated when more than one event occurs. These types of compound events are called independent and dependent events. Through this lesson, we will look at some real-world examples of how to calculate these probabilities.
8. Probability of Simple, Compound and Complementary Events
Simple, compound, and complementary events are different types of probabilities. Each of these probabilities are calculated in a slightly different fashion. In this lesson, we will look at some real world examples of these different forms of probability.
9. Statistical Significance: Definition & Calculation
Watch this video lesson to learn about statistical significance, and how it relates to surveys and other real world events. Also, learn how it is calculated, and how you can describe it to others.
10. What is Data Analysis? - Definition & Overview
In this lesson, we will learn about data analysis. We will define it, learn about the forms of data collection, and go through the process of data analysis. The lesson will conclude with a brief quiz to check your knowledge.
11. Types of Data Analysis
In this lesson, we will learn about data analysis. We'll look at a few types of basic data analysis, and then venture into more specific intense analysis. The lesson will conclude with some examples and a summary.
12. Data Analysis: Techniques & Methods
In this lesson, we'll learn about data analysis. We'll define the two methods of data analysis, quantitative and qualitative, and look at each of their various techniques. The lesson will then conclude with a summary and a quiz.
13. What is Data Analytics? - Definition & Tools
In this lesson, we'll learn about data analytics. We'll define it and learn about some of the many tools used for data analytics. The lesson is followed by a quiz.
14. Application of Statistics in Business
Statistics is used every day in business. This lesson describes some of the more popular applications to business statistics and provides real life examples of how it is used. Key vocabulary and terminology will also be discussed.
15. Chebyshev's Inequality: Definition, Formula & Examples
Chebyshev's inequality is used to measure the dispersion of data for any distribution. In this lesson, we look at the formula for Chebyshev's inequality and provide examples of its use.
16. Cumulative Distribution Function: Formula & Examples
This lesson introduces you to the cumulative distribution function. An easy-to-follow illustration is used to show you the formula and it's usefulness. We also look at some examples.
