Individual Variables

In the previous chapter we looked at individual variables; however, a sample may involve more than one variable. Moreover, data analysis is usually concerned with the relationships among two or more variables. These relationships might involve the same (e.g. numeric versus numeric) or different (e.g. numeric versus categorical) types of variable. In either case, we need to understand how the values of one variable relate to and/or depend on those of the other. Just as with single-variable analyses, we use both descriptive statistics and graphical summaries to explore such relationships. This chapter focuses on associations between variables. An association is any relationship between two variables that makes them dependent, i.e. knowing the value of one variable gives us some information about the possible values of the second variable. The main goal of this chapter is to show how to use descriptive statistics and visualizations to explore associations among different kinds of variables.

Learning in the pandemic period requires students to be able to use a variety of online learning media. Zoom, Google meet, Google classroom, and LMS platforms are the most frequently used media. Students' behavior to use learning media is influenced by perceptions of the learning media. This study aimed to describe the ease and usefulness perceptions that students feel about the various available learning media. This research is designed as quantitative research with a survey approach. Data analysis was carried out using descriptive statistics. The results show that students' perceived ease of learning media, namely Zoom, Google meet, Google classroom, and LMS, is perceived as relatively easy. Zoom is an application/platform that is considered the easiest of the other media, while LMS is considered more complicated than the other three media. Meanwhile, this study's results also show that the perspective of the usefulness of the learning media is considered to have good benefits. Zoom is the application/platform that is considered the most useful from other media, while LMS is considered less useful than the other three media.

It is well established that unique physiological information can be obtained by rapidly freezing cells in various functional states and analyzing the cell element content and distribution by electron probe x-ray microanalysis. (The other techniques of microanalysis that are amenable to imaging, such as electron energy loss spectroscopy, secondary ion mass spectroscopy, particle induced x-ray emission etc., are not addressed in this tutorial.) However, the usual processes of data acquisition are labor intensive and lengthy, requiring that x-ray counts be collected from individually selected regions of each cell in question and that data analysis be performed subsequent to data collection. A judicious combination of quantitative elemental maps and static raster probes adds not only an additional overall perception of what is occurring during a particular biological manipulation or event, but substantially increases data productivity. Recent advances in microcomputer instrumentation and software have made readily feasible the acquisition and processing of digital quantitative x-ray maps of one to several cells.

The objective of this study was to compare the cytotoxicity of a domestically-made light-cured orthodontic adhesive to a commercial adhesive, Transbond XT (3M Unitek, USA). An in-house orthodontic adhesive composed of a filler 60-70 weight % and a monomer ratio (BisGMA:TEGDMA) of 6:4 with 0.5% of photoinitiator was mixed. The potential cytotoxic effect of this experimental and a control adhesive was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay according to ISO 10993-5: 2009(E). The L929 cell line was grown in 96-well tissue culture plates (1x105 cells/mm3). Thin cured-resin discs of each material weighing 0.4 gram were prepared and incubated for 1, 3, 5, 7, 14, and 30 days in Dulbecco’s modified Eagle medium (DMEM) at 37°C and 95% humidity with 5% CO2. The percentage of cell viability was reported by descriptive statistics. The result showed that the cell viability of the experimental adhesive was higher than Transbond XT in all measured periods. The cytotoxicity of both the adhesives gradually decreased with the progression of time. In conclusion, the in-house adhesive showed a good biocompatibility since the first day following polymerization. On the other hand, Transbond XT started with a cytotoxic potential, then, turned to be non-cytotoxic after 5 days of curing.

The Impact

In this paper, the scope is to study whether and how the COVID-19 situation affected the unemployment rate in Greece. To achieve this, a vector autoregression (VAR) model is employed and data analysis is carried out. Another interesting question is whether the situation affected more heavily female and the youth unemployment (under 25 years old) compared to the overall unemployment. To predict the future impact of COVID-19 on these variables, we used the Impulse Response function. Furthermore, there is taking place a comparison of the impact of the pandemic with the other European countries for overall, female, and youth unemployment rates. Finally, the forecasting ability of such a model is compared with ARIMA and ANN univariate models.

Introduction: The changing proportion of older adults in society necessitates the need to determine the attitudes of health care professionals toward older adults. The purpose of this study was to explore attitudes of ageism and its correlates among health care professionals working with older adults. Method: This descriptive study was conducted in seven hospitals in five cities in Turkey. A total of 628 health care professionals participated in this study. The Fraboni Scale of Ageism (FSA) was used to collect data. Descriptive statistics, student’s t test, one-way analysis of variance and multivariate linear regression were used for data analysis. Results: The mean total score from the FSA was 56.9 ( SD = 8.0). Education (β = −.18, p < .001) and difficulty with the care of older adults (β = −.10, p < .05) were statistically significant predictors of the FSA score. Conclusions: The attitudes of health care professionals toward older adults were generally positive and affected by difficulty in providing care and the educational status of the health care professionals.
