Millar Biology statistics made simple using Excel Biology statistics made simple using Excel Neil Millar Spreadsheet programs such as Microsoft Excel can transform the use of statistics in A-level science Statistics is an area that most A-level biology students (and their teachers!) find difficult. The formulae are often complicated‚ the calculations tedious‚ degrees of freedom mysterious‚ and probability tables confusing. But in fact students need no longer grapple with any of these.

velocity of 350 feet per second. The gravitational force of Earth is pulling the rocket down at a rate of 16 feet per second per second. The formula for‚ s(t)‚ for the function that models the height of the water balloon at time t‚ in seconds‚ is s(t)= -16t2 + 350t + 4. We can determine how long it takes for the rocket to land from the graph where the function intercepts the x-axis because this is the value where the height of the rocket is 0 feet. From the graph‚ we can see that the rocket lands in 21

Powered by Cognero Use the slope formula to find the slope of the sides of the trapezoid. Use the slope formula to find the slope of the sides of the trapezoid. The slopes of exactly one pair of opposite sides are equal. So‚ they are parallel. Therefore‚ the quadrilateral ABCD is a trapezoid. ANSWER: ABCD is a trapezoid. 4. Determine whether ABCD is an isosceles trapezoid. Explain. SOLUTION: Refer to the graph of the trapezoid. Use the slope formula to find the slope of the sides of Page 1 the

relationship is a straight line relationship. In the form of an equation‚ this relationship can be expressed as Y = α + βX + e In this equation‚ Y is the dependent variable‚ and X is the independent variable. α is the intercept of the regression line‚ and β is the slope of the regression line. e is the random disturbance term. The way to interpret the above equation is as follows: Y = α + βX (ignoring the disturbance term “e”) gives the average relationship between the values of

Suellen Fonseca Physics 151 April 3‚ 2013 Questions and Answers: 1. Define uniform circular motion. A. Is an object in uniform circular motion accelerating? B. Define centripetal acceleration‚ and state its magnitude and direction. (2.0 points) Ans: An object moving at a constant velocity around a circular path is performing a uniform circular motion. The object’s path is considered to be tangent to the circle due to the fact that it is constantly changing position

2 periods ---July 1931 to June 2012 and July 1631 to June 2012. The theory’s prediction is that the intercept should equal to zero the slope should be the excess return on the market portfolio. The findings of this study are not substantiating the theory’s claim for the fact that in some portfolios the alpha is statistically significant with non zero value and in some regression models‚ the slope is not statistically significant. 1.
