A.
In Group 1, the mean count of trees is about 23.75 with a std. deviation of 4.84
In Group 2, the mean count of trees is about 14.08 with a std. deviation of 4.76
In Group 3, the mean count of trees is about 15.77 with a std. deviation of 5.43
There has a drastic change in the count of trees in plots that have never been logged (group 1) to plots that have been 1 year earlier (group 2)
B.
Data A
Mean 7.50090
Std. Dev 1.9371
Data B
Mean 7.50090
Std. Dev 1.9360
Dataset A and B have the same mean and almost the same standard
deviation. However dataset A appears to be skewed to the the left
whereas dataset B appears to be fairly symmetric with one large
outlier as shown in the dotplots.

Unit 6 Lesson 3 Classwork (Adapted from Math Vision Project) Data Distribution A lot of information can be obtained from looking at data plots and their distributions. It is important when describing data that we use context to communicate the shape, center, and spread. Shape and spread: Modes: uniform (evenly spread- no obvious mode), unimodal (one main peak), bimodal (two main peaks), or multimodal (multiple locations where the data is relatively higher than others). Skewed distribution: when most data is...

A. Introduction and Objective Every test has at least two sources of variation that affect the results of the test. The first source of variation is due to the experimental procedure, such as using two different testing machines that have different calibrations, or different observers reading the same equipment differently. This type of variation is often called the experimental error The second source of variation is inherent in the specimens (or sample population) themselves. In other words, no two specimens...

1 L, as a dynamical system (Notes from Assignment #2) We take our definition of dynamical system to be an "object" along with a specific set of modifications that can be performed (dynamically) upon this object. In this case, the object is a bi-infinite straight road with a lamp post at every street corner and a marked lamp (the position of the lamplighter). There are two possible types of modifications: the lamplighter can walk any distance in either direction from...

will work with up to 3 partners (similar to a lab group) to prepare a written report which analyzes kinetic data that has been provided to you. All student groups will receive data for the hypothetical reaction aAlE) products where a is a numeric variable and A is a chemical variable. The reaction therefore has the form of a decomposition reaction, in which a single substance forms one or more new substances. For consistency, all concentrations start out at 1.000...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
