Biology Enzymes IA Design Introduction: Enzymes are globular proteins, they are responsible for most of the chemical activities of a living organism. They act as catalysts, substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms, one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the…

will then create a bar graph showing teams who won at the end of the first period and won at the end of the third and teams who lost at the end of the first period and won at the end of the third. Using information from the bar graph, I will use the chi-squared test of independence to see whether the score at the end of the first period and the score at the end of the third period are independent. Procedure 1. For the dates of the 200 games, I placed slips of paper into a three boxes. In one…

Chi-Square Analysis Use a table to collect the results of the crosses you performed. Then start by examining the phenotypic ratios of offspring obtained to see if any patterns of inheritance are apparent. If any crosses seem to indicate that patterns exist, propose tentative hypotheses about the mode(s) of inheritance. Use these to deduce genotypes for all of the parent flies and to calculate expected ratios of offspring. If it is a sex linked trait, you should include the male and female versions…

The chi-square approach includes four steps: Hypothesis, analysis plan, sample data sample already provided in milestone 2 and results. Hypothesis Once the data was processed and displayed in excel, observations of data and pattern were obtained. By just looking at the display of data the relationship among variables are perceived; the type of class can be the independent variable and the dependent variables are the number of participants that might be influenced by another variable that can be…

Alma Guadalupe Luna Math IA (SL TYPE1) Circles Circles Introduction The objective of this task is to explore the relationship between the positions of points within circles that intersect. The first figure illustrates circle C1 with radius r, centre O, and any point P. r is the distance between the centre O and any point (such as A) of circle C1. Figure 1 The second diagram shows circle…

Chi-Square & Misuses The chi-square statistical measurement is an inferential statistic to determine differences among groups. It compares frequency observed with frequency expected. It does not determine where the differences are, just that they do exist. The chi-square measurement is used a lot in business to compare projected budgeted items with actual expense and revenue items to determine any significant differences that could indicate problems or areas for new innovations of products. The…
