Correlation Essays

Correlation techniques are used to find whether the electrocardiogram (ECG) is normal or abnormal. These correlation techniques could be further used to detect the type of abnormality present in the abnormal ECG. Reference ECG signals could be stored for all type of abnormalities and the test ECG signal if correlated with the stored references will give highest correlation percentage with the type of abnormality present in it. Arrhythmias are one of the abnormalities in ECG. Among various arrhythmias one of...

1 Introduction The scatterplot is a dominant graph used in science articles due to its proven usefulness in science and finding correlations (SCATTER BRAINED, 2018). Residual plots can be used to show further or less validity of scatterplots. This report will delve into the mathematics stated above to provide a conclusion to whether rainfall impacts the production of sugar cane and or sugar. This report will be about the impact rainfall has on tonnes of sugar cane and sugar produced...

Introduction Depreciation in the value of a car over time is a good example of a linear function with a proportional change in value over the cars age. For research purposes, in this investigation the values of two different makes and models of cars from the past nine years will be compared and explored through multiple mathematical concepts and ideas to determine if a linear function develops. To gather the data necessary for evaluating the depreciation rate of cars and...

Introduction: Since young, exercising has always been a part of my life. When I was 8, I was selected to join the development team and afterwards the school team for gymnastics. Regular physical exercise was something I had been engaged in since a very young age. However, after leaving primary school, I did not join a sport, and hence it led to a reduction in my exercise habits. Simultaneously, the amount of food consumed during my training days did not...

Humans are social in nature, involving with others and trying to figure out how different concepts work with regard to certain factors. It is like a network of comparisons, and that is how the human mind works too. For instance, a person who lives in a big and beautiful house is presumed to be rich, while a person who lives in a thatched house is assumed to be poor. This may be true is some cases, but not all. There...

Correlation coefficients are used in statistics to measure how strong a relationship is between two variables. There are several types of correlation coefficient. Pearson’s correlation (also called Pearson’s R) is a correlation coefficient commonly used in linear regression. If you’re starting out in statistics, you’ll probably learn about Pearson’s R first. In fact, when anyone refers to the correlation coefficient, they are usually talking about Pearson’s. Meaning A correlation coefficient of ‘1’ means that for every positive increase in one...

Correlation analysis is a statistical measure that indicates the extent to which two or more variables fluctuate together. It helps us in determining the degree of relationships between variables, according to, Hazewinkel, (1994). It does not, however, tell us anything about the cause and effect of the relationship, for instance, if there is a high degree of correlation between the variables. A variable in statistics is any characteristic number, or quantity that can be measured or counted. It is unknown...
