Question

Given the data to the left, which contains the age and the pulse rate for 38 female patients. Using excel, TI, or statcrunch to find and indicate the measures of central tendencies, the measures of variations and the five-number summary of the pulse rates only. Draw the box plot and the histogram for the pulse rates and the scatter plot using both columns.

Write a brief conclusion including:

· What do the central tendencies tell you about the data, is normal or skewed and why,

· What is true about the measures of variation, that is, is the variation large of small and why,

· What does the box plot and the histogram tell you about the data set, is it skewed or normal, does it agree with the central tendency conclusion above,

· What central tendency would you report? That is, what is the average pulse rate for this sample set?

· Does the pulse rate increase as the age increase? Sketch a scatter plot to determine this.

Measures of Central Tendencies:

Mean _________ Median ________ Mode ________

Measures of Variation:

Range_________ Variance __________ Std. Deviation ________

Five Number Summary:

Minimum Value ________ Q1 : _________ Q2: _______ Q3: _______

Maximum value: _____________

Answer 1

** Note that here i have used R software just commanding , the data's.

Minimum = 60 , Q1 = 68 , Q2 = 72 , Q3 = 80 , Maximum = 124
