Physics being an experimental science, we sought to learn how to prepare a lab and perform as a team accounting for errors and uncertainties and to reduce them. We gathered values for volume using Micrometer, gathered information on acceleration, velocity, and created a histogram using a PASCO motion sensor. A jumping experiment was also performed with a human and the motion sensor. Our main goal was to test the effects of human error and eliminating mechanical error.

Principal Components Analysis (PCA) and Canonical Correlation Analysis (CCA) are among the methods used in Multivariate Data Analysis. PCA is concerned with explaining the variance-covariance structure of a set of variables through a few linear combinations of these variables. Its general objectives are data reduction and interpretation. CCA seeks to identify and quantify the associations between two sets of variables i.e Pulp fibres and Paper variables.PCA shows that the first PC already exceeds 90% of the total variability. According to the proportion of variability explained by each canonical variable , the results suggest that the first two canonical correlations seem to be sufficient to explain the structure between Pulp and Paper characteristics with 98.86%. Despite the fact that the first the two canonical variables keep 98% of common variability, 78% was kept in the pulp fiber set and about 94% of the paper set as a whole. In the proportion of opposite canonical variable,there were approximately 64% for the paper set of variables and 78% for the pulp fiber set of variables kept for the two respectively.

Write a short summary of the third assignment here. In the summary include the question you answered, a few sentences to describe the nature of the problem. The problem statement or introduction should introduce the health issue that you are answering and what is known about the health problem. Also indicate why answering the question is important. Then write a few sentences about what databases you searched, and what were you search criteria (you should describe that in words, do not include any tables or figure here). Then write the results you obtained. Here, write briefly how many articles you originally retrieved and how many articles (five, but if not five then how many) articles you finally considered to be good enough to answer the question and which article you found best out of these five and why. Then briefly describe the nature of the article and write a few sentences as to why and how this article answered the main question you set out to answer in this assignment. Typically the summary will be one paragraph, but you can include more than one paragraph to break up the thoughts and ideas presented in your assignment. Try to be brief and capture the essential point in the assignment you write. Do not include any references or citations in this section.
