Chi-square distribution

23. This term refers to how data spreads out or disperses within a distribution. (Points : 1) |        Variability        Critical region        Range        Mode | 24. Relevant data that are expressed in numerical form are called: (Points : 1) |        Qualitative data        Quantitative data        Standard data        Multiplicative data | 25. It is not necessary to look at the frequency distribution if the mean, median, and mode are known. (Points : 1) |        True

LOM 5300 Statistical Analysis for Business Decisions Multiple Choice Questions Chapter 1 1. In a questionnaire, respondents are asked to mark their gender as male or female. Gender is an example of the a. ordinal scale. b. nominal scale. c. ratio scale. d. interval scale. ANS: b 2. The scale of measurement that is used to rank order the observation for a variable is called the a. ratio scale. b. ordinal scale. c. nominal scale. d. interval scale. ANS: b 3. Some hotels ask their guests to

Factor analysis According to Maria& Eva, the factor analysis is a technique in the statistics to observe variability in the correlated variables in terms of lowers number of unobserved variables, which is necessary for factorization (Maria& Eva, 2012). Dehak, Kenn, Dehak, Dumouchel, & Ouellet, further stated that, the factor analysis is useful technique to investigate the relationship between the variables in complex concepts and the main purpose of the factor analysis is to reduce the number of

and sepia and apterpous (mutants) were expected a 9:3:3:1 phenotypic ratio. The chi square value for the monohybrid was 3.843. We had a degree of freedom of 1. The nearest estimated value to our calculated value fell under the fifth percentile which is 3.84. Since these values are equal, we accept the null hypothesis and confirm the 3:1 ratio for the monohybrid cross. In the dihybrid cross, the calculated chi square value was 1.343. The degree of freedom happened to be 3. The nearest value fell

Please answer the following questions. The number of words have been specified in each question. Please provide at least one reference for each. Thank you. Suppose you hear an "old-timer" say, "Why, in my day, kids were much more respectful and didn't cause as much trouble as they do nowadays!" Formulate a hypothesis related to this statement that you could test. How would you test it? (100 words) Hypothesis: The rates of juvenile offenses were lower in 1961 than they were in 2011. Testing:

Table 9.2 Distribution of sample units Age-wise age of investor Total A1 A2 A3 A4 A5 Whether investor YES 65 121 66 51 60 363 NO 25 46 38 14 14 137 Total 90 167 104 65 74 500 From the above table 9.2 it conclude that highest number of investor comes under the age group of 31-40 years, A2 = 121 this is may be because of recent developments during post recession in share markets and mutual funds showed some what stagnant performance in negative trend of market . Table 9.3 Distribution of sample

directional change from generation to generation. This is seen in the chi-square probability distributions, where although the small population’s probability is considered non-significant the chi-square value was only 0.211 (Table 1) less than the significant chi-square value. The small population allele frequency (p) was non-directional and varied greatly between groups and generations (Figure 1). The large population chi-square value was noticeably larger and was affected more than the small population

Identify 3 methods statistical inference listed attached flowcharts. (1) Chi-square tests. (2) One-sample t test. (3) One-sample z test. b. Describe in detail each method and how you could use this method in health care administration. (1) Chi-square tests. This nonparametric test procedure operates by tabulating a variable into different categories and then computing a corresponding chi-square statistic (Chi-square tests, 2007). This so-called "goodness-of-fit test" is used to compare the
