The nctm's curriculum standards for statistics give a specific objective for students in grades 9–12: to “understand sampling and recognize its role in statistical claims” (NCTM 1989, 167). The use of random samples for estimation is a fundamental statistical concept. Random sampling and its consequences can be studied through simulated sampling activities. The nature of sampling variability, the influence of sample size on the quality of estimation, and the role of the underlying population distribution are ideas that can be illustrated with repeated sampling.

This study investigated the characteristics of Photo Fenton oxidation in comparison with Fenton oxidation in dark environments. The specific objective was to provide an in-depth understanding as to how the presence of UV would effect the reaction and its efficiency as compared to the Dark Fenton Oxidation. All reactions were carried out in batch mode at an initial pH of 3.5, with H2O2 in excess and iron in catalytic concentrations. The medium pressure mercury lamp (320-400 nm) was used as a UV source. The role of UV in Photo Fenton Oxidation of p-chlorophenol was found to be manyfold as compared to Dark Fenton Oxidation. It included the expedition of ferric ion reduction and the photolysis of H2O2, which exerted a direct impact on the p-chlorophenol degradation kinetics by enhancing the production of OH radical. Also included in the role was alteration of the quantity (and potentially quality) of intermediates, which would lead to a change in the decomposition kinetics in an indirect manner. Therefore, it was concluded that the performance of Photo Fenton Oxidation as compared to Dark Fenton Oxidation could vary in complicated ways depending upon the characteristics of target compounds and their intermediates.

An interactive microcomputer program was developed to aid the design of simple random sampling with or without replacement. The program determines: (1) sample size for a set of given conditions for up to 20 variables; (2) combinations of conditions that will yield a given samples size; and (3) the relationship between percentage error and sample size for a given set of conditions. Potential applications are illustrated with three simple examples. Key Words: sample size, simple random sampling

Background: Regular feelings of anxiety is a severe life and highly prevalent psychiatric disorder which becomes one of the major cause of death across the globe. Although the exact causes responsible for anxiety are not known only in Pakistan 44 % of the population is facing anxiety problems which leads to many other diseases and low quality of life. Objectives: To investigate whether the youth of Pakistan is facing anxiety problems, what are the major cause of anxiety, how anxiety can be managed, and to study the role of prayers in anxiety management.  Method: The researcher select 400 respondents from two universities of Lahore (the University of Central Punjab and Punjab University) through a systematic random sampling technique. In the first phase, the researcher filters those people who did not face an anxiety problem in the last month. Researchers collect data only from those respondents who can recall and face an anxiety problem in the last month. Results: Rate of anxiety among the youth of Pakistan is alarming, as (71 %) of the respondent said that they face anxiety problems. But there is a very significant relationship between prayers and anxiety management. Conclusion: The researcher concludes that prayers can be used to manage or reduce anxiety.

ABSTRACT Currently, there are no standardized treatments for cachexia or severe wasting. There is a growing consensus advocating multimodal interventions to address the complex pathogenesis and metabolic alterations in these conditions. This review examined multimodal treatments intended to alleviate and/or stabilize cachexia and severe wasting. The objectives of this review were to 1) identify multimodal interventions for the treatment of cachexia or associated wasting syndromes in patients with a chronic illness, 2) assess the quality of these studies, and 3) assess the effectiveness of multimodal interventions. Electronic databases including PubMed, MEDLINE, EMBASE, Scopus, Web of Science, Cochrane Library, CINAHL, PEDro, OpenGrey, and clinicaltrials.org were systematically searched using both text words and MeSH (medical subject heading) terms. The literature revealed a dearth of large, well-conducted trials in this area. Fourteen trials (n = 5 cancer, n = 5 chronic obstructive pulmonary disease, n = 4 chronic kidney disease) were included in this review. A total of 1026 patients were included across all studies; sample size ranged between 21 and 138 patients. Baseline and follow-up data were collected between 6 wk and 24 mo. All demonstrated some improvement in favor of the treatment groups, in relevant measures of body composition, nutrition, biomarkers, and functionality; however, caution should be applied due to the heterogenous nature of the interventions and small sample sizes. Overall, the evidence from this review supports the role of multimodal interventions in the treatment of severe wasting. However, randomized controlled trials with a powered sample size and sufficiently lengthy interaction period are necessary to assess if multimodal interventions are effective forms of therapy for improving body composition and nutritional and physical status in patients with cachexia and wasting. The protocol for this review is registered with Prospero (ID: CRD42019124374).

The dimension of soil augers needed to sample a seed bank of Chenopodium spp. (lamb's-quarters) was determined by randomly sampling a 1.35-ha area within a cornfield in Oxford County, Ontario. Sampling units of three different auger sizes (1.9, 2.7, and 3.3 cm in diameter) were collected. On a per volume basis, there were no significant differences between the three sizes of auger in estimating the number of lamb's-quarters seeds in the soil. Three sampling methods, systematic, stratified random, and cluster, were compared with random sampling in their capacity to minimize the sampling variance. Soil cores of 1.9 cm diameter and 15 cm deep were taken systematically at 3.5-m intervals to form a 32 × 32 matrix. Repeated sampling within the matrix using Monte Carlo techniques indicated that the estimate of sampling variance decreased with increasing sample size, regardless of the sampling method used. No fewer than 60 sampling units should be collected to quantify the seed bank of an abundant weed such as lamb's-quarters. The estimates of sampling variance of systematic and cluster sampling were clearly influenced by the sampling interval and the cluster's shape, respectively. This was attributed to the underlying seed distribution of lamb's-quarters in the soil that was clustered with patterns of high and low seed density parallel to corn rows. There were no significant differences between the estimate of sampling variance of random and stratified random sampling with a fixed sample size of 64 units.
