Chapter 10 and 12 Flashcards
Blank is a statistical process for determining the likelihood that is a given hypothesis is true
Hypothesis testing
The blank,denoted by Ha, is a mathematical statement that describes a population parameter, and it is the hypothesis that the researcher is aiming to gather evidence to support it is also referred to as the research hypothesis
Alternative hypothesis
The blank, denoted by Ho, is the statement that express the value currently believed to be true; it will always be a statement of equality
Null hypothesis
A blank is the value of the probability distribution it used to make a decision about the null hypothesis
Test statistic
A sample statistic is said to be blank if it is far enough away from the presumed value of the population parameter to conclude that it would be unlikely for the sample statistic to occur by chance if the null hypothesis is true
Statistically significant
The blank, denoted by Alpha, is the probability of making an error of rejecting the true null hypothesis in a hypothesis test
a=1-c
Level of significance
The blank is a probability associated with a test statistic. It is compared to Alpha to determine whether or not to reject the null hypothesis
P-value
A blank exists between two variables when the value of 1 are somehow associated with the values of another in some way
Correlation
A blank exists between two variables when there is a correlation and plotted points of pair data resulting in a pattern that can be approximated by a straight line
Linear correlation
The blank, p, is the parameter that measures the strength of a linear relationship between two quantitative variables in a population
Personal correlation coefficient
The blank,r2, is a measure of the proportions of a variation in the response variable (Y) that can be associated with the variation in the explanatory variable ( X).
