tendency. In cases of great skewness‚ use the median as the measure of central tendency to avoid distortion by extreme values. You can usually assess skewness by simply eyeballing a histogram. To be precise about measuring skewness‚ apply the Excel SKEW function to a data set. * If SKEW > +1‚ the data are positively skewed and the median is the better measure of central tendency. * If SKEW < -1‚ the data are negatively skewed and the median is again the better measure of central tendency

and structure There are three types of blood vessel‚ Arteries ‚ veins and capillaries. Each of them have different functions involved in carrying blood around the body . Arteries are blood vessels that transport blood away from the heart‚ veins are blood vessels that transport blood to the heart and Capillaries are extremely small vessels located within the tissues of the body that transport blood from the arteries to the veins. they must be constructed for carrying fluids over long distances‚

While traveling through the femoral vein‚ you will notice that it is one of the largest in the venal system. As you may also know the femoral vein will return oxygenated blood to the heart and lungs. From the femoral vein‚ we will be traveling up the external iliac vein. Once we enter the external iliac vein‚ we will be carried through the abdomen. From the external iliac vein we travel

see that Dick’s salary is an outlier compared to the mean. b) The median of these seven salaries is $23‚500. I got the median by first putting the numbers in order. Since it is an odd amount of numbers‚ I just find the center of the data after they were in order. This value does not really compare to all of the individual salaries; it has no relation other then it is just in the center. Dick’s salary does not compare to the median because it is the outlier‚ but mostly everyone else’s does because

The purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the

Q1. (a) ‘Statistics is the backbone of decision-making’. Comment. Ans.(a) Due to advanced communication network‚ rapid changes in consumer behavior‚ varied expectations of variety of consumers and new market openings‚ modern managers have a difficult task of making quick and appropriate decisions. Therefore‚ there is a need for them to depend more upon quantitative techniques like mathematical models‚ statistics‚ operations research and econometrics. Decision making is a key part of our day-to-day

According to a study done by the National Center for Public Policy and Higher Education‚ “college tuition and fees increased 439 percent from 1982 to 2007 while median family income rose 147 percent.”(“College May Become Unaffordable for Most in U.S.”). This means‚ that while the cost of the median family did go up by 147 percent‚ tuition cost went up nearly 2.9 times more. The drastically increasing cost of college is effecting many students all across the United States. Whether
