JAYSON C.LUCENA CREATOR

Use this test to compare differences between two independent groups when dependent variables are either ordinal or continuous. Select one: d. Mann-Whitney test d. Statistical Test Valid for both non-Normally distributed data and Normally distributed data Select one: a. Non Parametric Test The parametric test is the hypothesis test which provides generalizations for making statements about the ____________________ of the parent population. Select one: c. Mean Parametric test is mainly based on differences in medians Select one: False Uses parametric scale Select one: d. Interval The intent is to determine whether there is enough evidence to "reject" a conjecture or hypothesis about the process. The conjecture is called the ______________________ Select one: a. Null Uses non parametric scale Select one: a. Ordinal A skewed distribution is one reason to run a parametric test. Select one: False If you have parametric data, you can run a Wilcoxon rank-sum test to compare means Select one: True False It is the most frequently occurring variable in a distribution. Select one: b. Mode

Inferential Statistics The most complicated distribution would list every value of a variable and the number of persons who had each value Select one: False It is defined as the middle of a distribution in a ranked data Select one: a. Median It provides a visual representation of the data. Select one: a. Graphical Method

What is the median of the scores of the subject Language? Select one: d. 2.5 The advantage of using non probability sampling is the accuracy of the statistical methods after the experiment Select one: True False

Snowball sampling can be effective when a sampling frame is easy to identify. Select one: True False

Question text When the standard deviation is small, the curve is tall and narrow; and when the standard deviation is big, the curve is short and wide Select one: True False The t-statistic rests on the underlying assumption that there is the normal distribution of variable and the mean in known or assumed to be known. Select one: True False Stratified sampling is used when we might reasonably expect the measurement of interest to vary between the different subgroups, and we want to ensure representation from all the subgroups Select one: True False Inferential statistics always talks in terms of statistics, but this can be made highly reliable by designing the right experimental conditions Select one: True False Cluster sampling can be more efficient that simple random sampling, especially where a study takes place over a wide geographical region. Select one: True The total area under the normal curve is equal to 2. Select one: False Uses non parametric scale Select one: c. Ordinal Use when you want to find a correlation between two sets of data. Select one:

If your data isn’t normally distributed, you can’t run the Kruskal-Wallis test., but you can run the nonparametric alternative–the ANOVA Select one: True False It is defined as "the statistical measure that identifies a single value as representative of an entire distribution." Select one: a. Central Tendency It is the term given to the analysis of data that helps describe, show or summarize data in a meaningful way such that, for example, patterns might emerge from the data. Select one: a. Descriptive Statistics

It is the test of association for ranked variables. Select one: d. Goodman Kruska's Gamma It is a method that allows researchers to infer information about a population based on results from a subset of the population, without having to investigate every individual Select one: b.

Mode Parametric test is mainly based on differences in medians Select one: False The formula of sample mean is Select one: False Quota sampling has the advantage of being time-and cost-effective to perform whilst resulting in a range of responses (particularly useful in qualitative research). Select one: False Which of the following would not allow you to calculate a correlation? Select one: a. a curvilinear relationship between X and Y

Select one: True False Parametric tests can provide trustworthy results with distributions that are skewed and nonnormal Select one: True Measures of central tendency are ways of describing the central position of a frequency distribution for a group of data. Select one: True Parametric type of test. Select one: a. ANOVA Test If the sample data are consistent with the null hypothesis, but consistent with the alternative, then we reject the null hypothesis and conclude that the alternative hypothesis is true. Select one: False

It arise out of the fact that sampling naturally incurs sampling error and thus a sample is not expected to perfectly represent the population Select one: d.
