I found pictures of Terex™ dump trucks on the Internet. I also ran a survey of students and determined that the college students prefer Kikkoman to Yamasa.Īs a child my son liked articulated mining dump trucks. I eventually showed that the mean price per milliliter for Yamasa was significantly higher than Kikkoman. I recorded Yamasa and Kikkoman soy sauce prices and volumes, working out the cost per milliliter. I walked into a store back in 2003 and noticed that Yamasa™ soy sauce appeared to cost more than Kikkoman™ soy sauce. I later incorporated this data into the fall 2007 final. I later find that a linear correlation does exist, and I am able to show by a t-test that the faster jumpers have statistically significantly higher jump counts. I used my stopwatch to record the time and total jump count. I saw that I could begin to predict jump counts based on the starting rhythm of the jumper. Then I noticed that faster jumpers attained higher jump counts than slower jumpers. With a mode, median, mean, and standard deviation. The number of jumps for each jumper until they fouled out was being recorded on the wall. I walked into a school fair and noticed a jump rope contest. We all walk in an almost invisible sea of data. Hypothesis testing against a known population mean.Introduction to the normal distribution.
