- scatterhist(x,y) creates a 2-D scatter plot of the data in vectors x and y, and displays the marginal distributions of x and y as univariate histograms on the horizontal and vertical axes of the scatter plot, respectively. example.

- @Huck Smith ...err then that is not a histogram. A histogram is a crude estimate of the probability density function of a univariate (in the conventional sense of a histogram) variable. Hence, in a histogram the x-axis represents the single variable and the y-axis is the estimate of the density of the data at values on the scale of x. By the sounds of it, you want a barplot() – Gavin Simpson Sep 15 '11 at 8:09. The information about plot(), write(), and read.csv() were very useful to me.

histogram (ˈhɪstəˌɡræm ) noun. a statistical graph that represents the frequency of values of a quantity by vertical rectangles of varying heights and widths. The width of the rectangles is in proportion to the class interval under consideration, and their areas represent the relative frequency of the phenomenon in question.

Histogram A histogram is an accurate graphical representation of the distribution of numerical data. It is an estimate of the probability distribution of a continuous variable (quantitative variable) and was first introduced by Karl Pearson. It is a kind of bar graph.

Using graphs A graph commonly consists of two axes called the x-axis (horizontal) and y-axis (vertical). Each axis corresponds to one variable. The axes are labelled with different names, such as Price and Quantity. The place where the two axes intersect is called the origin. The origin is also identified as the point (0,0). A point on a graph represents a relationship. Each point is defined by a pair of numbers containing two co-ordinates (x and y). A co-ordinate is one of a set of numbers used to identify the location of a point on a graph.

- How to read the Histogram. A histogram is a graphical representation of the pixels exposed in your image. The left side of the graph represents the blacks or shadows, the right side represents the highlights or bright areas and the middle section is mid-tones (middle or 18% grey).

Histogram For the histograms used in digital image processing, see Image histogram and Color histogram. A histogram is a graphical representation of the distribution of numerical data. It is an estimate of the probability distribution of a continuous variable (quantitative variable) and was first introduced by Karl Pearson.

- Answer   From my understanding, a histogram is a form of graphical interpretation of data. This simply means a picture to reflect data. For example, if you have data like … , 20 students in your class smokes while another 30 doesn't smoke, you can represent this into a histogram. (a simple picture to depict the data).

- The scatter plot here reveals. 1  a basic linear relationship between X and Y for most of the data, and. 2  a single outlier (at X = 375).

- How crosstabs differs from a scatterplot under the Graphs Menu. 1  Like crosstabs, scatterplot portrays the joint distribution of two variables. 2  Unlike crosstabs, scatterplot is designed for continuous variables which distribute cases across unique points in space.

Scatter Plot A graph of plotted points that show the relationship between two sets of data. In this example, each dot represents one person's weight versus their height.

Scatter Plots A Scatter (XY) Plot has points that show the relationship between two sets of data.In this example, each dot shows one person's weight versus their height. (The data is plotted on the graph as  Cartesian (x,y) Coordinates ). Scatter (XY) Plot has points that show the relationship between two sets of data.

Histogram Histograms are sometimes confused with bar charts. A histogram is used for continuous data, where the bins represent ranges of data, while a bar chart is a plot of categorical variables. Some authors recommend that bar charts have gaps between the rectangles to clarify the distinction.

- 1. The purpose of a scatter plot is to show the type of relationship, or correlation, that exists between two sets of data. a. For instance, a positive correlation means that as the value of one set of data increases, the other data will also increase.he purpose of a scatter plot is to show the type of relationship, or correlation, that exists between two sets of data.

Scatter plot The data is displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis. This kind of plot is also called a scatter chart, scattergram, scatter diagram, or scatter graph.or a set of data variables (dimensions) X 1, X 2, ... , X k, the scatter plot matrix shows all the pairwise scatter plots of the variables on a single view with multiple scatterplots in a matrix format. For k variables, the scatterplot matrix will contain k rows and k columns.

Histogram Total area of the rectangles in a histogram represents the total frequency. A histogram with more number of class intervals is more effective in depicting the structure of the frequency distribution. The relative frequency table is a compact numerical way to present how the data is distributed.If the frequencies are plotted as columns, the resulting plot is called a histogram. A frequency distribution shows the number of items in each of several overlapping classes.he relative frequency table is a compact numerical way to present how the data is distributed.

- More About Scatter Plot. 1  A scatter plot describes a positive trend if, as one set of values increases, the other set tends to increase. 2  A scatter plot describes a negative trend if, as one set of values increases, the other set tends to decrease. 3  A scatter plot shows no trend if the ordered pairs show no correlation. scatter plot is a graph made by plotting ordered pairs in a coordinate plane to show the correlation between two sets of data.

- With density being the ratio of mass per volume, the gas density of the balloon thus varies only with its volume (when mass is held constant). If we squeeze the balloon, we compress the air and two things will happen: the air pressure in the balloon will increase. the density of the air in the balloon will increase.

Histogram A histogram is a graphical representation of the distribution of numerical data. It is an estimate of the probability distribution of a continuous variable (quantitative variable) and was first introduced by Karl Pearson.he etymology of the word histogram is uncertain. Sometimes it is said to be derived from the Ancient Greek ἱστός (histos) – anything set upright (as the masts of a ship, the bar of a loom, or the vertical bars of a histogram); and γράμμα (gramma) – drawing, record, writing.

Histograms and histographs The bars are of equal width and correspond to the equal class intervals, while the height of each bar corresponds to the frequency of the class it represents. The histogram is used for variables whose values are numerical and measured on an interval scale. It is generally used when dealing with large data sets (greater than 100 observations). A histogram can also help detect any unusual observations (outliers) or any gaps in the data.

Statistics chpt 3 what is the difference between a histogram and a bar graph. histogram is a frequency distribution with the score on the X-axis and the frequency on the Y-axis except that the frequencies are notes as rectangular bars. Bar graph differs from the histogram in that dimension represents the independent variable and the other represents the dependent variable.

Histogram A histogram is an accurate representation of the distribution of numerical data. It is an estimate of the probability distribution of a continuous variable and was first introduced by Karl Pearson. It is a kind of bar graph. To construct a histogram, the first step is to bin the range of values—that is, divide the entire range of values into a series of intervals—and then count how many values fall into each interval. The bins are usually specified as consecutive, non-overlapping ...

Why Use a Box and Whisker Plot? A box and whisker plot is a graphical method of displaying variation in a set of data. In most cases a histogram provides a sufficient display; however, a box and whisker plot can provide additional detail while allowing multiple sets of data to be displayed in the same graph. Some types are called box and whisker plots with outliers.
