Question

1. Based on the histogram and statistics, please describe the 1) shape, 2) center, and 3) spread for the distributions of height and weight.

2. Are the shapes for the distributions of height and weight different? Why? In your explanation please refer to both the histograms with the normal curve and the appropriate statistic.

3. Can you calculate the mean for gender? Why or why not?

1. Please describe the pattern found in the boxplots for both height and weight (separately). How do the medians compare between males and females? Are males taller or heavier on average than female?  

2. Looking at the boxplot again, determine if there is more variability for males or females with regard to both height and weight?

Explanation / Answer

Q1.

i) The distribution of the height is negatively skewed while that of weight is positively skewed (not symmetric).

ii) The center of both the variable is Median. since mean mean is not located at the center of the data for skewed distribution.

iii) The spread of the Height is 13.89 and that of weight is 14.55.

Q2 the shapes for the distributions of height and weight different since the distribution of Height is negatively skewed while of weight it is positively skewed.

Q3 we can not compute the mean of Gender since Gender is the Nominal variable (Qualitative). Since we can not perform arithmatic operation on nominal data.

Q1

From the boxplot we say that the distribution of height and weight of male is negatively skewed. While the distribution of height of female is negatively skewed and that of weight is positively skewed.

From the Boxplot it is clear that male are heavier as well as taller than females.

Q2 With regards to the data The variability among the male is more than female for both height and weight.
