Comparison of ANOVA F and K Tests in Terms of Type III Error Rates
(Turkish)

Mehmet MENDEŞ
Çanakkale Onsekiz Mart University, Faculty of Agricultrue Animal Science - Çanakkale

There exist another type of error, called Type III error, in addition to Type I and Type II error in two-tailed hypothesis testing. Type III error (g) is the probability of getting the direction wrong. The effect of Type III error on test power is more pronounced especially when sample sizes are small. In this study a simulation study was conducted to compare Anova F and K tests with respect to Type III error rates. At the end of 100000 simulation trial it was seen that the probability of a rejection in the wrong direction (Type III error) decreased as sample size and population mean differences increased. This was more obvious for ANOVA F test. Also it was seen that probability of the Type III error rate increased as number of groups and heterogeneity of variance increased. It is more pronounced with respect to K test. When samples were taken from three Chi-square with 3 df populations under variance heterogeneity (1:3:5), the probability of Type III error rate vary 0.54-1.54% for F test and 0.92-4.37% for K test. When number of group increased to four and variance ratio was 1:2:4:6, the probability of Type III error rate vary 1.63-5.01% for F test and 2.15-14.6% for K test. When samples were taken from three exponential (0.50) populations under the same experimental conditions, tTpe III error rate increased especially in terms of K-statistics.

Key Words: Type III error, confidence interval, power of test, homogeneity of variance, nonnormal distribution

Net blotch caused by Drechslera teres is an important disease of barley. There is no study regarding the biology of the pathogen in Turkey. Therefore, studies were conducted to elucidate some parts of the biology of the pathogen under Ankara conditions. Conidia, conidiophores and pseudothecia of the pathogen were observed on the leaves left on the ground and buried. These propagules were more common on the leaves left on the ground. No ascospores were detected. Pycnidia were detected in cooled incubator studies. In a cooled incubator, fungal cultures survived 0ºC and -10ºC and fungus in diseased leaves survived -10ºC. It appears that fungus can survive during the winter months in Ankara and conidia has an important role in the infections.

Manufacturers aim at choosing the most efficient one among available opportunities. This could be possible only under the condition of having a productive or service system. Factory arrangement is one of the factors, which affect the productivity directly. Any mistake in the factory arrangement cause an increase in the fixed cost, transport expenses and work accidents. Problems of factory arrangement have been solved by testing in a manufacturer factory of the agricultural machines. The collected data have been determined on the available settlement of the factory. These data have been used to find the solution for the best factory settlement by using a computer program developed by J. R. King (The Computer Supported Classification Method with Degree Sequence). By using a cell production system, the control of workers on the machinery increased and distance between the machinery decreased. Moreover, 44.38% working space was gained in the factory. The aim of this arrangement was to obtain maximum benefit from production capacity of the factory, to use working space effectively, to avoid a blockage in production process, and to reduce unnecessary movements of workers in order to carry things.

This research investigated the effects of different ethephon doses on seed yield, yield components and oil ratio was carried out in Department of Field Crops, Faculty of Agriculture, Ankara University during 2001 and 2002. The experiment was established as randomized blocks with three replications. In this study, five different ethephon doses (0, 50, 100, 200 ve 400 g/ha) were applied to variety Dinçer 5-118 which was in the jointing stage. According to the research results, it was determined that plant height, one thousand kernel weight and seed yield per plant were decreased with increasing ethephon doses and number of side branches was fluctuated. Number of capitula, number of seed per capitula and seed yield per decare increased with ethephon dose of 50 g/ha. With regard to seed yield per decare, the highest value was obtained from 50 g/ha with 110.3 and 131.3 kg/da in 2001 and 2002, respectively. Moreover, the highest seed yield per decare obtained from dose of 50 g/ha which gave the highest number of capitula per plant and number of seed per capitula. However, oil ratio of seed with shell was decreased with increasing ethephon doses. It was observed that higher doses than 50 g/ha ethephon resulted in decrease on these traits and influenced adversely yield components.

Willow scale, Chionaspis salicis L. (Hom.: Diaspididae) is a major pest of poplar trees in Van. To understand population structure and density, and to determine reasons for population fluctuation of C. salicis, its population dynamics were investigated and a life table was constructed in 2000. Data were collected in three poplar tree plantations. Sampling was carried out every fortnight and 5 cm2 parts of the stem of poplar trees were used as sampling units. C. salicis had one generation per year in Van. Generation mortality was extremely high and approximately 71% of it occurred during the egg-crawler stage. Egg-crawler deaths caused by various factors were the most important mortality factors underlying fluctuations in the population. Parasitism and predation contributed to total generation mortality at the pre-ovipositing female stage and caused mortality rates of 14.7% and 18.6% respectively. Zaomma lambinus (Walker) (Hym.: Encyrtidae) and Inostemma sp. (Hym.: Platygasteridae) were found as parasitoids, and Chilocorus bipustulatus L. (Col: Coccinellidae) and Temnostethus sp.

Some of them that have been identified by morphologic and biological characteristics, but still have discriminate some variations due to unknown genotypic or phenotypic causes. Genetic diversity studies using Random Amplified Polymorphic DNA (RAPD) technique were carried out in a set of 10 olive cultivars (Ayvalik, Derik Halhali, Domat, Gemlik, Kilis Yaglik, Manzanilla, Memecik, Nizip Yaglik, Sari Ulak and Tavsan Yuregi) from the Turkish Olive Germplasm Bank of the Olive Research Institute in Izmir, Turkey. Analysis of PCR products was achieved by using the simple matching coefficient and UPGMA clustering. Primers were identified and used in combination to discriminate between different varieties. The diversity of RAPD patterns demonstrated the biodiversity among varieties. Also some pomological and biochemical analysis were done in order to support the results of the genetic variability. Among cultivars, Derik Halhali showed the big differences, according to the genetic and biochemical results.
