LESSON II: LINEAR CORRELATION ANALYSISObjectives:●1.Identify independent anddependent variables.Construct a scatterplot.2.Determine the strength andmagnitude of a correlationcoefficient.Calculate the Pearson'scorrelation coefficient.Activity (Collaboration)Determine the independent variable and the dependent variable.An athletic trainer wants to be able to predict the cardiac output from hisclients' level of exercise.IntroductionCorrelation analysis has touchedquantitative research in many ways.Relationships among variables arevery important because they canexplain certain phenomena that wouldeventually contribute to the whole well-being of humanity.4.Independent variable:Dependent variable:The more time spent studying, the higher the GPA is.Independent variable:Dependent variable:Jne3.A student is absent from class most of the time. Therefore, he got a lowscore on the long test given by the teacher.Independent variable:_Dependent variable:The smaller the ball, the faster it drops to the ground.Independent variable:Dependent variable:Chapter 5: Data Management Tools 93

A researcher is investigating the effectiveness of two weight loss treatments. The number of patients attending Treatment A and Treatment B are 30 and 32 respectively. The patients’ weight losses (in Kg) after a two-month treatment period are recorded and shown in Table 1: What type of research design you think this research should be classified? Explain your answer. Based on the research objective of the study, identify the: Independent and dependent variables of this research. Scale of measurement of each of the independent and dependent variables. For EACH of the treatment, determine/construct the following measures and histograms of weight losses using SPSS or any suitable statistical analysis tool: Mean Median Range Histogram d. Based on the histograms of weight losses produced in (c), briefly describe: The shape of distribution of weight losses for EACH treatment. How does the distribution of Treatment A differ from Treatment B e.…
