Is Variance Sensitive To Extreme Values? Since it uses only the extreme values, it is greatly affected by extreme values. The variance is the average squared deviation from the mean. It usefulness is limited because the units are squared and not the same as the original data. What is sensitive to extreme values? The mean
What Are Standard Error Bars? Error bars are graphical representations of the variability of data and used on graphs to indicate the error or uncertainty in a reported measurement. … Error bars often represent one standard deviation of uncertainty, one standard error, or a particular confidence interval (e.g., a 95% interval). What kind of error
What Are The 4 Measures Of Variability? Four measures of variability are the range (the difference between the larges and smallest observations), the interquartile range (the difference between the 75th and 25th percentiles) the variance and the standard deviation. What are the key measures of variability? Range: the difference between the highest and lowest values.
What Are The 4 Measures Of Central Tendency? The four measures of central tendency are mean, median, mode and the midrange. Here, mid-range or mid-extreme of a set of statistical data values is the arithmetic mean of the maximum and minimum values in a data set. What are the 5 measures of central tendency? Measures

What Do Measures Of Variability Tell Us? Measures of variability (sometimes called measures of dispersion) provide descriptive information about the dispersion of scores within data. Measures of variability provide summary statistics to understand the variety of scores in relation to the midpoint of the data. What does the measure of variability indicate? Measures of variability.
What Do You Mean By Descriptive Statistics And Inferential Statistics? Descriptive statistics provides us the tools to define our data in a most understandable and appropriate way. Inferential Statistics. It is about using data from sample and then making inferences about the larger population from which the sample is drawn. What is meant by descriptive
