Explanation / Answer
Q5. Mean is based on all values of the data. It is strongly affected by extreme values . Where as median is middle value of the data and it is less affected by the outliers.
"When extreme scores are present, the median is __more accurate__ than the mean at representing the center value of the set."
Q6. The standard devation is measure of variation. It is a amount of spread of data. When extreme scores are present variation is increases.
So,
The standard deviation is _sensitive to__ extreme scores.
Q7. The standard devation is measure of variation. It is a amount of spread of data.
The larger the standard deviation, the _more spread out scores are__ in a distribution."
Q8. The standard deviation is spread of from mean. It tells us distance of score from mean.
The standard deviation can be used to help us _find the center position in a distribution___.
Q 9. Range = Largest valueof data - smallest value of data. It is measure of variation.
The range is used almost always to get a _ very general__ estimate of how wide or different scores are from one another.
Q10. The standard devation is measure of variation. It is a amount of spread of data around mean.
The standard deviation represents the average amount of __variability__ in a set of scores.
