Statistics is a very interesting field. To participate in a data science team, you need some basic understanding of the language. There are several terms you need to be familiar with as you explore statistical analysis. They aredoi:10.1007/978-1-4842-2253-9_4Doug Rose...
Finding value in big data isn’t only about analysing it, it is a process of discovery which requires insightful analysts to recognize patterns and trends, and for business leaders to ask the right questions, to make informed assumptions, to accurately ...
However, we did find statistical agreement between the means of α 1 exponents from long and short segments, even for segments involving just 50 RR intervals. According to results of synthetic series, the 95% confidence interval found for the variation of α 1 using segments with 300 samples ...

Statistical analysis was performed using PRISM (GraphPad Software, La Jolla, CA, USA). All data sets were assumed to be normally distributed which was confirmed using the Shapiro-Wilks test to test for normal distri- bution. Student's t-test (two-tailed, unpaired) was performed where ...
Separate summaries were provided to describe the characteristics of study population, methodologies of SA used, statistical methods used to identify significant covariates among clusters, and strategies employed for recognising and managing data quality issues. 2.7.

The main routine statistical analyses can be carried out from start to finish on a minicomputer with basic language capability and ⩾ 32 000 bytes of random access memory. However, no statistical software packs for minicomputers are ever complete enough for exhaustive analysis of most problems. ...
We compared the leaf profitability between biomes and leaf habits (deciduous and evergreens) using one way analysis of variance. The statistical analyses were performed using Statistica (v 8.028). Companies’ database and profitability calculations Data for companies were obtained from the ‘Sistema ...
Various technical resources have recently been developed to audit biases in models and datasets (Hagendorff2020; Lee and Singh2021; Mehrabi et al.2021). These tools allow for identifying biases at individual and group levels through statistical metrics and even allow mitigation during the training st...
It must be noted that aggregating crash severity data for spatial analysis may affect the results depending on the extent of the study area (such as a county, zip code, or a specific intersection or segment of highway). Hence, we decided to conduct a study on disaggregated crash severity ...
