The most common measures of central tendency are the mean, median, and mode.<\/p>\n<p>A measure of data spread is a value that describes how spread out the data are. The most common measures of data spread are the range, interquartile range, and standard deviation.<\/p>\n<p>A confidence interval is an interval of values that is likely to contain the true value of a population parameter.<\/p>\n<p>In statistical hypothesis testing, the null hypothesis is the hypothesis that there is no difference between the two groups being compared. The alternative hypothesis is the hypothesis that there is a difference between the two groups being compared. The p-value is used to determine whether or not to reject the null hypothesis. If the p-value is less than or equal to the significance level, then the null hypothesis is rejected. This means that there is evidence to support the alternative hypothesis.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;A measure of central tendency&#8221; option2=&#8221;A measure of data spread&#8221;
