Vermiculite and Vigna Radiata Background Information: Vermiculite is a common material used in the planting of various types of plants. It is said to be efficient in soil aeration‚ and as a soil medium in germination. Generally it’s PH is 7.0 and varies slightly around the world (Grant‚ A. 2016). The property of Vermiculite tested in this experiment is soil aeration. This is extremely important for plant growth because if a plant is not aerated well CO2 will accumulate and slow down the growth of

PEARSON PRODUCT MOMENT CORRELATION COEFFICIENT Definition It is the measure of the linear correlation between two variables X and Y It is the measure of the strength of a linear association between two variables and is denoted by r. It tells you how strong the linear correlation is for paired numeric data e.g. height and weight. The Pearson correlation coefficient‚ r‚ indicates how far away all these data points are to this line of best fit. Development It was the imagination and idea of Sir Francis

View the Causation and Correlation Presentation. Compare and contrast causation and correlation in a 200- to 300-word post. Explain whether each of the following may be classified as a causation or correlation. Justify your reasoning. Identify any possible lurking variables that may be present. Wealthy people are thin. This is an example of correlation. It is a case where people associate being wealthy with having more healthy habbits. In my opinion it is just conjecture and personal opinion

Linearity: A linear correlation coefficient factor was obtained between the peak area used and the absorbance Verses concentrations of lamivudine‚ zidovudine and nevirapine. The calibration curves were linear for concentrations between 15-150 µg/ml. The linearity of the calibration curves was validated by the values of the correlation coefficients (r2). The correlation coefficients were 0.999 for lamivudine‚ 0.999 zidovudine and 0.999 for nevirapine. The results of the linearity experiment are listed

Studies have shown that the only correlation between SAT scores and college grades is in the freshman year.

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
