A bar graph that shows the frequency data within equal intervals?
a histogram
Why are the bars on the histogram touching and not separated?
Your observation is correct for a histogram that involves numbers. The width of each bar indicates the span of that group -- the left-hand edge is the lowest value in the group and the right-hand edge is the highest. A histogram indicates how many counts that fall within the specific boundaries of a bar as indicated by the bar width (the bar height indicates the count). For example, if I decide that the bar width should be one unit each, I construct the histogram with bars one unit wide. However, when the count is zero for some intervals, then there will be a gap of one unit wide. I probably increase my bar width to avoid gaps, so that all bars are touching. Under certain abnormal circumstances will I see gaps. Now the story is different for bar graphs. They are normally made of categories (for example, apples, pears, and oranges). In this case, the gap between bars is fine. ============================
How do you calculate absolute frequencies?
Absolute frequencies are calculated by first identifying intervals based on your data and then identifying the number of values within your data set that lie within these interval. Relative frequencies divide the absolute frequencues by the number of values in the set. It is a good practice to provide the absolute frequencies, perhaps in a bar chart of relative frequencies as a number above each bar.
What does it mean if a statistic is significant?
It means, within the laws of statistical analysis, that the statistic occurs more frequently than the baseline number which is considered "random" for the particular application. It happens more frequently than "random" - hence there is, or may be, something "significant" about that.
The percentile corresponding to a given x is computed by adding the 0.5 to number of values below x and dividing this value by the total number of values within the data set true or false?

What is a bar graph that shows the number of data items that occur within each interval?
It could be a bar graph or a frequency polygon. Or, if the intervals are of different sizes, a histogram.
What type of scores represents a histogram?
A histogram represents the distribution of scores in a dataset by organizing them into equally spaced intervals or bins along the horizontal axis, and displaying the frequency or count of scores within each bin on the vertical axis. The scores on the horizontal axis could be any type of numerical data, such as test scores, heights, or ages.

How many perfect intervals are there?
Within an octave there are four perfect intervals: perfect unison (P1), perfect fourth (P4), perfect fifth (P5), and perfect octave (P8).
