Calculating correlation values for categorical data In order to find the correlation values for the fields in our data set‚ The Pearson Correlation Coefficient was used. This requires that the data in both fields be quantitative. But what if we were looking to calculate the correlation on two given fields that were say‚ numerical and categorical‚ or even both categorical. The Point Biserial coefficient is a special case of The Pearson Correlation Coefficient; it is a branch of PCC although they

Two Variable Inequality Katherine Courtney MAT221 Phil Le August 25‚ 2013 Inequalities are equations that can be used to determine not just what something could equal but what something cannot equal. It tells us what the relative size is of two values and if they are big or small‚ too much or not enough. Inequalities could make it easier to determine how much someone might need of something in order to make a certain amount of something‚ while also determining

simultaneously or even in a different order. The scientific method has the following characteristics: observation of phenomena‚ formulation of a question‚ pattern recognition‚ developing theories‚ experimentation and summarizing information. The first two steps of the scientific method involve observation and description of a phenomenon or group of phenomena and then formulating a question. The description must be reliable‚ replicable and valid (Wikipedia.org). Scientists will try and find a cause and

Inequalities are equations that can be used to determine not just what something could equal but what something cannot equal. It tells us what the relative size is of two values and if they are big or small‚ too much or not enough. Inequalities could make it easier to determine how much someone might need of something in order to make a certain amount of something‚ while also determining how much more might be needed or how much be left.

TWO-VARIABLE INEQUALITY MAT 221 Joseph Oslakovic February 16‚ 2014 TWO-VARIABLE INEQUALITY This week we are learning about two-variable inequalities as they pertain to algebraic expressions. The inequality can be graphed to show the values included in and excluded from a given range of numbers. Solving for inequalities such as these is a critical skill in many trades which can save or cost a company a lot of time and money. Ozark Furniture Company can obtain at

Two Variable Inequality MAT 221 11 May 2012 The purpose of this week’s assignment is to determine how many maple rocking chairs the Ozark Furniture Company can make. We will also plot the inequalities of this on a graph. Here is the information and first set of problems for the text: Maple rockers. Ozark Furniture Company can obtain at most 3000 board feet of maple lumber for making its classic and modern maple rocking chairs. A classic maple rocker requires 15 board

Two Variable Inequality Robin Bettasso Mat 221 January 20‚ 2013 a) Let ‘c’ be the number of classic maple rocking chairs and ‘m’ be the number of classic maple rocking chairs that Ozark Furniture Company make. b) Here we have given that a classic maple rocker requires 15 board feet of maple‚ and a modern rocker requires 12 board feet of maple. We have ‘c’ classic maple rocker‚ so total maple required for classic maple rocker chair = 15c board feet. And we have ‘m’ modern maple
