Statistical Parameters: A perennial stream is a stream that has water flowing in it all the time. The data set presented in Table 1 represents a sample of stream flows in a perennial stream for a 45-day period. These stream flows were measured using a flow meter that has a precision of t0.1 Cfs. Find the following statistical parameters for the sample data given in Table 1. 1. a. Central Tendency i. Mean = the average value of the random variable. ii. Median the value of the random variable that is in the middle of the sample set. Mode-the value of the random variable that occurs most frequently. iii. b. Dispersion i. ii. C. Asymmetry Variance- an average measure of the deviation about the mean squared. Standard deviation - an average measure of the deviation about the mean. Skew - a measure of the symmetry or asymmetry of the sample data about the mean. i. Graphical Representation of Data: Given the data presented in Table 1, develop the following 2. Histogram - use an interval of 2 Cfs Box Plot-are there any outliers? a. b.

    Discrete vs. Continuous Random Variable: You will notice that there is most likely no mode for the sample data set presented in Table 1. The reason there are not multiple instances of exactly the same value of the random variable is due to the continuous nature of the random variable. Continuous random variables are random variables whose value can take on infinitely many values-the value of which is typically governed by the precision of the device used to measure the...
