Is acceleration and velocity the same?
Velocity is the rate of change of position with respect to time, whereas acceleration is the rate of change of velocity. Both are vector quantities (and so also have a specified direction), but the units of velocity are meters per second while the units of acceleration are meters per second squared.
Can there be 2 modes?
In a set of data, the mode is the most frequently observed data value. There may be no mode if no value appears more than any other. There may also be two modes (bimodal), three modes (trimodal), or four or more modes (multimodal).
What is the range of a data set?
In statistics, the range is the spread of your data from the lowest to the highest value in the distribution. Along with measures of central tendency, measures of variability give you descriptive statistics for summarizing your data set. The range is calculated by subtracting the lowest value from the highest value.
What if there are 2 medians?
If there is an even number of numbers locate the two middle numbers so that there is an equal number of values to the left and to the right of these two numbers. If there is an even number of numbers add the two middles and divide by 2. The result will be the median.
How do you find Q1?
Q1 is the median (the middle) of the lower half of the data, and Q3 is the median (the middle) of the upper half of the data. (3, 5, 7, 8, 9), | (11, 15, 16, 20, 21). Q1 = 7 and Q3 = 16. Step 5: Subtract Q1 from Q3.
How do you find the median with an even n?
This can be found by taking the value of the (n+1)/2 -th term, where n is the number of observations. Else, if the number of observations is even, then the median is the simple average of the middle two numbers. In calculation, the median is the simple average of the n/2 -th and the (n/2 + 1) -th terms.
How do you find the median of N 2?
Then if there are an odd number of numbers in the list the median can be found by counting in from either end of the list to the (n + 1)/2nd number. This will be the median. If there are an even number on the list then average the n/2 and the (N + 2)/2 numbers. In general, the median is at position (n + 1)/2.
