- A researcher studied 5050 adults daily screen time. She had them record the amount of hours (rounded to the nearest hour) they spent looking, listening or reading at computer or cell phone daily. The frequency table below shows the results. Hours of Screen Time Frequency 7 5 8 6 9 4 10 5 11 8 12 10 13 9 14 3 The researcher found that the mean number of hours of the data set was 10.7210.72. She wants to also find range and standard deviation. Find the range of the data set.range = Find the standard deviation of the data setstandard deviation = Round your result to two decimal places.Which is NOT a correct statement about mean, median, standard deviation, or interquartile range? a. Mean is more affected by changes in extreme observations b. Median is less affected by changes in extreme observations c. Standard deviation is less affected by changes in extreme observations d.
