Calculate z score outlier - Study guides, Class notes & Summaries

Liberty university edco 735 week 2 quiz (Answered) Complete Verified Solution A two-tailed outlier for the t distribution must have a t score equivalent to the: highest 5% or lowest 5% of the t distribution only the highest 5% of the t distribution only the lowest 5% of the t distribution highest 2.5% or lowest 2.5% of the t distribution In order to calculate the mean you must: multiply each score by itself take the square root of the sum have at least interval level of measureme...

CHAPTER 3 MEASUREMENTS, MISTAKES, AND MISUNDERSTANDINGS SECTION 3.1 SIMPLE MEASURES DON’T EXIST FREE RESPONSE QUESTIONS 1. Explain why even the simplest kind of measurement, such as finding your height, still presents complicated issues. ANSWER: ANY REASONABLE ANSWER OK. EXAMPLES: THE ACCURACY OF YOUR MEASUREMENT DEPENDS ON YOUR MEASUREMENT TOOL; HOW TALL YOU STAND WHEN YOU MEASURE; WHETHER OR NOT YOU WEAR SHOES, ETC. 2. Describe one of the issues that you would need to think about when...

I am using x to predict y. When I know the value of x, the mean-squared-error of my estimate of y is less than when I don't know x. - answers-x explains some of the variance in y If the SSmodel is greater than the SSresidual... - answers-the model accounts for more than 50% of the total variance What is the coefficient of determination? - answers-The proportion of variance accounted for in the dependent variable by the predictor variables. What is the relationship between r and beta in...

What is a dotplot? - ANSWER-A graphical display which shows "dots" for each point. It's good for categorical data- ie data classified into categories. What's the difference between categorical and quantitative data? - ANSWER-Categorical data fits into various categories; whereas, quantitative data has numerical values associated with it. What is a bar chart? - ANSWER-A display for categorical data which indicates frequencies or percents for each category. What are histograms? - ANSW...
