Aim of the Study
This study wants to see the relationship between lbm, rcc, wcc, ferr, bmi, ssf, ht, wt, hc and pcBfat. In continuation also want to check the relation between sex and sports.
Literature
A research has been done to see the relation of immunological and Haematological parameters with judo athletes (Hazratian et al., 2020). Haematological parameter and BMI with some other factors shows the importance on insulin resistance in North East Italy (Barrazoni et al., 2014). Variations in the size of athletes corresponding to different characteristics of blood is studied in Australia (Telford and Cunningham, 1991).This study also wants to see the relation among different factors of haematology, height and weight.
Data
Data is taken from the R library of DAAG. It has the information on 202 athletes in Australia to show the variations in the size of athletes corresponding to different characteristics of blood. Variables are defined as; lbm (lean body mass in), rcc (red blood cells count ), wcc (white blood cells count), ferr (plasma ferritins), bmi (body mass index), ssf (sum of skin folds), ht (height), wt (weight), hc (hematocrit), pcBfat (percent Body fat).
Statistical Analysis
This study utilizes correlation, regression and chi square to test the objective of the study. Following are the scatter plot represents the graphical relationship between lbm, bmi, ssf, rcc, ht and wt. All these graphs show the linear relationship to each others. This study shows the graphs which have linear relationship except those have functional relation.
Correlation
Now we will check that how these variables are correlated to each others. We can see this relationship on the basis of correlation. Correlation gives the linear relationship between two variables. Value of correlation coefficient tells the degree of linear association between two variables and it occurs -1 to +1. If the value is near...
