Residuals Date: _____________________ Introduction The fit of a linear function to a set of data can be assessed by analyzing__________________. A residual is the vertical distance between an observed data value and an estimated data value on a line of best fit. Representing residuals on a___________________________ provides a visual representation of the residuals for a set of data. A residual plot contains the points: (x‚ residual for x). A random residual plot‚ with both

there are no direct connections between any of the computers‚ although multiple hubs or switches can be added to increase the number of computers that may be connected to the network. A bus topology is the minimum complex network configuration it creates use of a single transmission medium called a coaxial cable. The star topology consists of shielded twisted pair wire (STP) or unshielded twisted pair wires (UTP). Due to the high cost of STP wire‚ most networks use UTP‚ however‚ STP wire must be
