that childhood events can have on adult life. My passion for quantitative psychology came after I enrolled in my Psychological Methods class. This inspired me to expand my knowledge of statistics and go outside the psychology department to enroll in Linear Regression, Analysis of Variance and other advanced statistics courses. I gained the ability to run statistical analyses in multiple packages such as R, SAS, and SPSS. These classroom experiences along with applied research and evaluation experience

I would like to propose a class entitled Analyzing Political Science Statistics, that would be offered through the Statistics Department as an Honors College class. This class would prepare students to analyze the types of statistics they would be looking at if they worked for a government agency or an agency that prepared statistics about topics, such as a president's approval rating. This class would add variety to the math classes that are offered by the Honors College since most of the math classes

Hansen Mechanical Contractors (HMC) is a large construction company who has changed the way sick time and personal time off (PTO) is paid and taken. In past years (up until 2013) sick time was only able to be taken in the calendar year and if not taken would be lost. Each employee was given seven sick days per year. Sick time could not be rolled over or cashed out at the end of the year. HMC decided starting January 1, 2014 that they would change this policy in hopes of giving their employees

Methods Sampling biota The biological community was sampled every two months from June 2014 to April 2015 across three spatial scales in Carlingford lough, Ireland. Sampling took place in Mill Bay (54°03.519 'N, 006°05.687 'W) in June, August, October and December 2014; as well as in February and April 2015 (Figure 1). Figure 1. Sampling occurred at Carlingford lough (a), in the extensive mudflat area of Mill Bay (b), at three spatial scales delineated by differences in mean lag between samples

Statistics is defined as a branch of mathematics used to analyze, explain summarize as well as interpret what we observe- in order to make sense or meaning of our observations. Every day in life we encounter information that originates from diverse forms and ways. This means that to make this information to have sense, there is the need to use statistics. However, due to its focus and empirical on applications, statistics is classically considered a distinctive mathematical science rather than a

Results We divide our analysis of the impacts of migration on how children allocate their time in the short-run in two parts. In the first part, we discuss the results of the effects of internal and international migration on children’s time outcomes using the treatment effect models, and in the second part, we present the results of the analysis of time allocated to non-school related activities and total studying time using SUR and Heckman models. All of the models predict the number of hours allocated
