Arithmetic average of a distribution of numerical values. Values may be discrete or continuous in nature. - Answer Mean Means that there a lot of very high or very low values in the observations that distort the calculated mean - Answer Skewing More complex analysis used in developing control charts for the display of some PI data. - Answer Standard deviation

CFA Level 1 - 101 Must Knows 368 Questions with Verified Answers Addition Rule of Probability - CORRECT ANSWER ADDITION: P(A or B) = P(A) + P(B) - P(AB) Roy's Safety First Criterion - CORRECT ANSWER Safety First Ratio = (E(R) - Rₜ) / σ Larger ratio is better If (Rₜ) is risk free rate, then it becomes Sharpe Ratio Sharpe Ratio - CORRECT ANSWER Sharpe Ratio = (E(R) - RFR) / σ Larger ratio is better If (Rt) is higher than RFR, then it becomes Safety First Ratio Centra...

Frequencies Just the count or number of observations in each category. Abbreviated as 'n' or 'f' Relative Frequency The number of times a particular observation occurs divided by the total number of observations. Frequency Distribution A summary of the numerical counts of the values or categories of a measurement. Cumulative Frequency The number of observations with a value less than the maximum value of the variable interval. Cumulative Relative Frequency Master...

The main purpose of descriptive statistics is to Summarize data in a useful and informative manner Which word is NOT part of the definition of descriptive statistics? Predicting A marketing class of 50 students evaluated the instructor using the following scale: superior, good, average, poor, and inferior. The descriptive summary showed the following survey results: 2% superior, 8% good, 45% average, 45% poor, and 0% inferior. c. Most students rated the instructor as poor or ave...

descriptive Statistics computed to reveal characteristics of the sample and to describe study variable How to describe a sample create a frequency distribution of the variable or variable being studied - is a plot of one variable, whereby the x-axis consists of possible values of that variable , and the y - axis is tally of each value Inferential Statistics computed to draw conclusions and make inferences about the greater population, based on the sample data set.
