Open University Business School. Discuss different forms of dependency and correlation that we might find in our datasets. Explore why it might sometimes be problematic to get a good measure of correlation. Chapter 10. Outline . Section 10-1 Introduction. Section 10-2 Scatter Plots. Section 10-3 Correlation. Section 10-4 Regression. Section 10-5 Coefficient of Determination and Standard Error of the Estimate. Once you know the correlation coefficient for your sample, you might want to determine whether this correlation occurred by chance.. Or does the relationship you found in your sample really exist in the population or were your results a fluke?. Coefficient B: the algebraic sum of Bi and Bp. . Induced B (Bi) . Caused by magnetism induced in the vertical soft iron components around the compass . Varies with the latitude as the vertical component of the earths field . What is Correlation Analysis?. Testing the Significance of the Correlation Coefficient . Regression Analysis. The Standard Error of Estimate . Assumptions Underlying Linear Regression. Confidence and Prediction Intervals. Objective. : To look for relationships between two quantitative variables. Scatterplots. Scatterplots. . may be the most common and most effective display for data. . In a scatterplot, you can see patterns, trends, relationships, and even the occasional extraordinary value sitting apart from the others.. Correlation. A statistical way to measure the relationship between two sets of data.. Means that both things are observed at the same time.. Causation. Means that one thing will cause the other.. You can have correlation without causation. Prepared by T.O. . Antwi. -Asare . 2/2/2017. 1. Correlation and Regression . Correlation. Scatter Diagram,. Karl Pearson Coefficient of Correlation. Rank Correlation. Limits for Correlation Coefficient. Summary of the measure of the characteristics of individuals in groups.. A descriptive statistic talks about a single characteristics within a given group. Lots of descriptive statistics are summarizing lots of characteristics but all within a given group.. Correlation. A statistical way to measure the relationship between two sets of data.. Means that both things are observed at the same time.. Causation. Means that one thing will cause the other.. You can have correlation without causation. Setting up and executing an experiment.. QPOE. 2. Question. Prediction. Evaluate. Observation. Explanation. Knowledge probe.
