The prevalence of work-related musculoskeletal disorders in dental hygienists is significantly higher than that of the general population. The purpose of this study was to evaluate the effect of explorer weight on dental and dental hygiene students' tactile discrimination when exploring. A randomized controlled clinical trial utilizing a dual dependent statistical design was used to collect dat...

The aim of this communication is to analyse the process of estimation of the adequate time unit in financial series. The problem in time aggregation is the loss of information, that will be acceptable if it is possible to fit a financial model. We present an example of time aggregation problems in Financial Time series over the daily Deutsche Aktienindex (DAX) using three comparative methods: d...

We examine what purpose a dialog metric serves and then propose empirical methods for evaluating systems that meet that purpose. The methods include a protocol for conducting a wizard-of-oz experiment and a basic set of descriptive statistics for substantiating performance claims using the data collected from the experiment as an ideal benchmark or “gold standard” for comparative judgments. The...

Methods: Eleven healthy adults, ranging in BMI from 20.20 to 24.77 kg*m , volunteered to participate in the study. They wore the selected criterion pedometer Yamax SW-200 (SW), which is considered the ‘‘gold standard’’, the Garmin Vivofit (GV), Medisana ViFit (MV), Accupedo application (AC) and Pedometer 2.0 application (PD), for a 24-h period, under free-living settings. Data were analyzed usi...

Server transaction logs containing complete click-through data from a digital library of primarily image-based documents were analyzed to better understand user search session behavior. One month of data was analyzed using descriptive statistics and network analysis methods. The findings reveal iterative search behaviors centered on result views and evaluation and topical areas of focus for the...

Method Two electronic databases (PEDro, OTSeeker) were searched using ‘child’, ‘paediatric’ OR ‘adolescent’, limiting years to 2000-2011. Records were included if participants were 0-18-years-old with movement impairments; intervention involved OT/PT; AND primary outcome related to the child’s activity/participation as specified by the WHO. Data were extracted on: study characteristics, interve...

The eld of statistics can be divided into two branches, descriptive statistics and inferential statistics. Descriptive statistics, as its name suggests, is concerned with describing a population, or a sample from that population, in terms of numerical measures that are computed from data. Such a numerical measure is called a statistic. If the data used in the computation comes from the whole po...

Many statistical analyses benefit from the assumption that unconditional or conditional distributions are continuous and normal. Over fifty years ago in this journal, Lord (1955) and Cook (1959) chronicled departures from normality in educational tests, and Micerri (1989) similarly showed that the normality assumption is met rarely in educational and psychological practice. In this paper, the a...

Materials and methods Nation-wide CHILD plans to recruit pregnant women at 4 Canadian sites including Winnipeg where 1000 participants will be recruited over the next two years. Participants (including those in the ‘vanguard’, pilot group) completed questionnaires about their health, environment and SES. These data were described using descriptive and x analyses. General Manitoba population dat...

We document the descriptive statistics and detailed regression outputs for educational attainment and measured 2D:4D ratios, based on the RLMS data (20th round, conducted in 2011-2012). Regression analysis is conducted using STATA 13, gologit2 which is a special code for the generalized ordered logit regression in STATA environment. We provide graphs of differences in means of 2D:4D ratios by e...
