Can You Have Negative ML? Given a certain l, ml is an interval ranging from –l to +l, so it can be zero, a negative integer, or a positive integer. What does it mean if ml 0? The letter ml designates the orientation of the orbital in space. It can have values between -l and
Can Amplitude Ever Be Negative? The amplitude or peak amplitude of a wave or vibration is a measure of deviation from its central value. Amplitudes are always positive numbers (for example: 3.5, 1, 120) and are never negative (for example: -3.5, -1, -120). Can a sine graph be negative? The intersections of this graph and
How Do You Tell If An Absolute Value Function Opens Up Or Down? The leading coefficient of the function will determine whether the graph opens up or down. If your leading coefficient is positive, the graph will open up and your vertex will be a minimum point. If a>0 (positive), the graph will open up.
Is Chi Squared A Test Of Difference? Pearson’s chi-squared test is used to determine whether there is a statistically significant difference between the expected frequencies and the observed frequencies in one or more categories of a contingency table. Is chi-square a test of difference or association? The Chi-Square Test of Independence determines whether there is
What Is Considered A High Covariance? Covariance gives you a positive number if the variables are positively related. You’ll get a negative number if they are negatively related. A high covariance basically indicates there is a strong relationship between the variables. A low value means there is a weak relationship. What is the range for
What Causes Positive Skewness? What causes positive skewness? Another cause of skewness is start-up effects. For example, if a procedure initially has a lot of successes during a long start-up period, this could create a positive skew on the data. (On the opposite hand, a start-up period with several initial failures can negatively skew data.)
