Terms in this set (100)Q&A Exponential Regression - Stat- Edit- L1 and L2 Stat- Calc- ExpReg (#0) Standard Deviation - small- data close together large- data spread out
Shape: Symmetric - The data on the graph is evenly spaced out.
Shape: Skewed Right - The data on the graph starts large from the left and
gets smaller as it goes to the right.
Shape: Skewed Left - The data on the graph starts small from the left and
gets larger as it goes to the right.
Shape: Uniform - The data on the graph is the same amount at each
interval.Mean - Only a good measure of center for symmetric data Median - (middle) Better measure of center for skewed data or data with an outlier
Terms in this set (100)Q&A "R" - Correlation Coefficient. It tells how good of a fit your scatter plot is to your line of best fit. -1 < r <1 Strong Negative - R is closer to -1 Strong Positive - R is close to 1 Weak Correlation - R is close to 0 Residual - Actual-Predicted
Residual Plots: Scattered means data is a good fit. Pattern means data is a
bad fit.Function - A relation where each x-value has only one y-value.Domain - X-values (input) Range - Y-values (output) Positive - Interval(s) of x where graph is above the x-axis Negative - Interval(s) of x where graph is below the x-axis
Terms in this set (100)Q&A Increasing - Interval(s) of x where graph is going from left to right Decreasing - Interval(s) of x where graph is going down from left to right End Behavior - When x increases, what does y approach?When x decreases, what does y approach?Relative Max - Highest y-value in a specific part of a graph Sequences - A list of numbers whose domain is all positive integers (make sure to say this when you are asked to write any rule for a sequence!) Arithmetic - Has an adding pattern.
Arithmetic: Explicit Rule - An = a1 + (n-1)d
Arithmetic: Recursive Rule - An+1 = An + d, a1 = first term
Geometric - Has a multiplying pattern
