In “regular” mathematics, a parameter refers to a value within an equation that is transferred throughout the equation. For example,mandbare parameters in the slope equationy=mx+b. However, the parameter definition in statistics is quite different. Parameters in statistics are used to describe ...
NORTH SLOPE BASIN – WHAT CAN STATISTICS TELL USVERON, James
What is the definition of Pearson Correlation Coefficient?The Pearson product-moment correlation coefficient depicts the extent that a change in one variable affects another variable. This relationship is measured by calculating the slope of the variables’ linear regression. The value of Person r can ...
Statistics are everywhere. From the news to the classroom, we are constantly surrounded by data that can help us gain a better understanding of any given topic. But exactly what is a statistic? In its simplest form, it is a fact or piece of data from a study of a large quantity of nu...
Recent statistics suggest 30% or more of college students cheat. If a class is graded on a curve, cheating hurts others’ grades. Even if there is no curve, cheating "poisons" the classroom, and others may feel pressured to join in. ("If I don’t cheat, I can’t compete with those...
If so, in what direction? Is there evidence of any extreme outliers? d. V2129 2. Pick two of the variables and/or charts from question 1. Write an explanation for your results in a way that would be easily understood by a layperson who isn't familiar with statistics. What does it ...
Linear Regression:The slope of the regression line is proportional to the standard deviation of y and inversely proportional to the standard deviation of x. Covariance: Sxy Answer and Explanation:1 SXX is the sample corrected sum of squares. It is the sum of the square of the difference betwee...

In the least-squares line=5-1x, what is the value of the slope? Choose one. When x changes by 1 unit, by how much does y change? What is the equation of the line that passes through the points (5, 12) and (5, 16)?
One of the goals of statistics is the organization and display of data. Many times one way to do this is to use agraph, chart or table. When working withpaired data, a useful type of graph is a scatterplot. This type of graph allows us to easily and effectively explore our data by...
