Find the mean, median, and mode for the scores in the following frequency distribution table: X f 5 2 4 5 3 2 2 3 1 0 0 2 The mean (to two decimal places) is , the median is , and the mode is . Based on the three values for central tendency, what is the most likely shape for this distribution of scores? The distribution is because the mean is the median and the median is the mode.

Q.2. The frequency distribution is a table that divides the data values into classes and shows the number of observed values that fall into each class. By converting data to a frequency distribution, we gain a perspective that helps us see the forest instead of the individual trees. Hence, the data is presented using charts and figures is widely followed method in descriptive statistics. In this connection, you are required to explain the meaning of histogram, frequency polygon and presents...
