Lin Article Critique: Part 3 Anne Hermanns Liberty University Lin Article Critique: Part 3 Critique or Result: Numbers 1, 2, 4, 5, and 10 Comparing the result study composed by Lin, Enright, Krahn, Mack, and Baskin (2004) with Pyrczak’s (2008) evaluation, elements are missing from Lin et al.’s (2004) article. For example, Pyrczak (2008) indicates the importance of percentages reported to be accurate without misleading the reader. Lin et al. (2004) determined the end number of participants in the follow up study decreased from 40 to six. The information given is misleading the audience because the data is not consistent throughout the entire study.
Ans: The experimental groups mean posttest depression scores (mean 13.36) was 0.64 points lower than its baseline mean score (mean 14.00). This was not an expected finding because it was not hypothesized that after the completion of the empowerment program, the experimental group’s depression skills would not improve. This finding indicates that the empowerment intervention has a negative impact on the depression of ESRD patients. 4. Compare the mean baseline and posttest depression scores of the control group.
The number of digits they had to recall was increased until the participant was unable to recall them accurately. His results found that the average digit span was five to nine items suggesting that the short term memory is limited. One limitation of Baddeley’s study into the capacity for the short term memory is that the study lack ecological validity. This is because the way in which the short term memory was used in the study did not correspond to how it is used in everyday life. This being said, the study does provide results in which can be analysed and as a result help to aid memory.
And according to our data, our actual yield is 0.5g CaCO3. Thus, our percent yield is 73.5%. Our percent yield was close to 100%, but not very close. I believe the error lies in human error, as well as instrumentation sensitivity. Our scale only measures to grams accurately, and could have not accurately represented the .68g of CaCO3, or we could have lost the solid precipitate in the process of the experiment.
It was possible that interference from other trigrams caused the poor recall. Baddeley et al (1975) carried out an experiment involving capacity of the STM, to study word-length effect on immediate memory span. He wanted to see if people could remember more short words rather than long words in a serial recall test, and prove that pronunciation time, determines the capacity of short-term memory. The reading speed of the participants was measure; they were then shown sets of five words on a screen. These words were taken from either one syllable set or polysyllabic words.
Which gene(s) were expressed less in Grandpa Joe’s lung cells? How do you know? * Genes three and six were expressed a lot less since they were not being expressed in the wet lab test and there ratios also were very low. The ratio of gene two was equal to one which means it’s not affected. Were there any genes not expressed in either cell type?
Describe the clinical importance of this relationship. variance = r^2 = (0.15)^2 = 0.0225 = 2.25% This is not considered clinically important since the variance is less than 9%. 6. Which two variables in Table 2, have the weakest correlation, or r value? Which relationship is the closest to this r value?
b. potential independent variables that are held constant. c. measured by the researcher. d. probable behavioral causes. 6. One reason a valid experiment may produce null results is a. the range of levels in the independent variable was insufficient to show an effect.
The mice with anti-IL-17 were had lower IL-17 levels, higher levels of A. fumigatus as measured by rRNA both at 24 and 48 hours versus the isotope mice without neutralized IL-17. Sample size was small and could have been larger. This experiment could have been better designed. Perhaps a randomized, double-blind, placebo-controlled design would better validate the results. P values were only cited in some of the results.
Following a delay, first items are remembered ________________ (better/less well) than last items. 6. The best retrieval cues come from the associations formed at the time we ____________________ a memory. 7. In some cases, old information facilitates our learning of new information.
