The scatter plot that I made showed a positive correlation which means that as the calories go up, the amount of fat goes up to. The slope of the data was 6/100, which means for every six grams of fat there were one hundred calories. Some may say that fast food restaurants provide

Looking at the stem-and-leaf plot, it is obvious there is a big difference between some of the letters. The percentage of relative frequency for the letters ranges from 0% to 13.4% meaning that while some letters are not used at all, some are used very frequently. Letters like E, T

Descriptive Statistics kWh 1st Hour Operational Day This data set has a p-value of much less than .05 so it is classified as skewed, or not normally distributed. In this case the Median and the IQR are better indicators of the distribution. Central Tendency: Mean = 113.76; Median = 108; Mode = 128 Dispersion: Standard Deviation = 39.05; IQR = 60; Range = 169 Number: n = 147 Min/Max: 53/222 Overnight Low OAT in F° This data set is distributed normally.
